The picture of the triangle ΔDEF is attached below.
A triangle can be defined as a basic polygon which has 3 sides.
The sum of all the interior angles of a triangle is given by 180°.The area of any triangle is calculated by [tex]\frac{1}{2}[/tex] × base × height.In a right-angled triangle the side opposite the largest angle which is 90° is called the hypotenuse.Pythagoras' theorem states that the sum of the squares of the legs of aright-angles triangle is equal to the square of the hypotenuse of the triangle.In the given ΔABC we see that AC is the hypotenuse and the two sides AB and AC are the legs of the triangle.
m∠B=90°
The ΔDEF is drawn such that m∠E=90° and AB=DE and EF=BC .
Therefore we can say that the two triangles are congruent by SAS axiom of congruency.

A whole salmon, weighing 7 # 6 oz, costs $2.74/#. The fillets are removed, boned, and trimmed. The head, bones, and all trim is thrown into the trash. What is the total value of the remaining fillets, which now weigh only 4 # 15 oz? What is their price per pound? What is the salmon’s yield percentage? If the next salmon weighs 6 # 14 oz, how much boneless salmon fillet would you expect to yield from it after fabrication?
Answers
Using proportions, it is found that:
The total value of the remaining fillets is of $13.53.The price per pound is of $2.54.The salmon’s yield percentage is of 66.95%.You would expect to yield 4.6 pounds of boneless salmon fillet from the next salmon weighing 6 # 14 oz.What is a proportion?A proportion is a fraction of a total amount, and the measures are related using a rule of three. Due to this, relations between variables, either direct(when both increase or both decrease) or inverse proportional(when one increases and the other decreases, or vice versa), can be built to find the desired measures in the problem, or equations to find these measures.
Before beginning the problem, we have that the symbol # represents a pound, which has 16 ounces.
The remaining fillets weight 4 # 15 oz = 4 pounds + 15/16 of a pound. Hence, considering the cost of $2.74 per pound:
4 x 2.74 + 15/16 x 2.74 = $13.53.
The total value of the remaining fillets is of $13.53.
The price per pound is still the same, of $2.54.
The yield is of 4 pounds + 15/16 of a pound = 4.9375 pounds out of 7 + 6/16 = 7.375 pounds, hence the percentage is:
4.9375/7.375 x 100% = 66.95%.
The salmon’s yield percentage is of 66.95%.
Hence, for 6 + 14/16 = 6.875 pounds, the yield would be of:
0.6695 x 6.875 = 4.6 pounds.
You would expect to yield 4.6 pounds of boneless salmon fillet from the next salmon weighing 6 # 14 oz.

Rita’s recipe for berry pies requires blueberries, raspberries, and strawberries. The ratio of cups of blueberries to cups of raspberries is 1 : 3. The ratio of cups of raspberries to cups of strawberries is 4 : 3. A batch of eight berry pies has a total of 25 cups of berries. How many cups of strawberries are in each pie?
Answers
Using proportions, it is found that there are 1.125 cups of strawberries in each pie.
What is a proportion?A proportion is a fraction of a total amount, and the measures can be related using a rule of three, which derives from proportional relationships.
Due to this, relations between variables, either direct(when both increase or both decrease) or inverse proportional(when one increases and the other decreases, or vice versa), can be built to find the desired measures in the problem, or equations to find these measures, involving operations such as division and multiplication, as they involve unit rates.
For this problem, from the ratios, we have that:
The ratio of cups of blueberries to cups of raspberries is 1 : 3, hence, for each 4 cups, 1 is blueberry and 3 is raspberry.The ratio of cups of raspberries to cups of strawberries is 4 : 3, hence, for each 7 cups, 4 are raspberries and 3 are strawberries.The least common multiple of 3 and 4 is 12, hence, multiplying 4 by 3, the ratio is:
Raspberries : Strawberries : Blueberries = 12 : 9 : 4
Meaning that our of 12 + 9 + 4 = 25 cups, we have that:
12 cups are of raspberries.9 cups are of strawberries.4 cups is of blueberries.There amounts are for 8 pies, hence, for a single pie:
9/8 = 1.125 cups.
There are 1.125 cups of strawberries in each pie.

The second matrix in the definition of [tex]f[/tex] is singular, since
[tex]\sin(\pi) = -\cos\left(\dfrac\pi2\right) = \tan(\pi) = 0[/tex]
[tex]\cos\left(\theta+\dfrac\pi4\right) = \sin\left(\dfrac\pi2 - \left(\theta+\dfrac\pi4\right)\right) = \sin\left(\dfrac\pi4-\theta\right)=-\sin\left(\theta-\dfrac\pi4\right)[/tex]
[tex]\cot\left(\theta+\dfrac\pi4\right) = \tan\left(\dfrac\pi2 - \left(\theta+\dfrac\pi4\right)\right) = \tan\left(\dfrac\pi4 - \theta\right) = -\tan\left(\theta-\dfrac\pi4\right)[/tex]

In other words, it's antisymmetric; [tex]A^\top=-A[/tex]. It's easy to show that [tex]\det(A)=0[/tex] if [tex]A[/tex] is 3x3 and antisymmetric.
The other determinant reduces to

Hence
[tex]f(\theta) = 1 + \sin^2(\theta) \implies f\left(\dfrac\pi2\right) = 1 + \cos^2(\theta)[/tex]
With [tex]g[/tex] defined on [tex]\left[0,\frac\pi2\right][/tex], both [tex]\sin(\theta)[/tex] and [tex]\cos(\theta)[/tex] are non-negative. So

The angles in a triangle are in the ratio 1 : 2 : 3.
a) Show that the triangle is a right-angled triangle.
b) The hypotenuse of the triangle is 19 cm long.
Calculate the length of the shortest side in the triangle.
Answers
Answer:
a) the largest angle is 90°, making it a right triangle
b) the shortest side is 9.5 cm long
Step-by-step explanation:
You want the largest angle and the shortest side in a triangle whose angles are in the ratio 1 : 2 : 3.
AnglesLet x represent the smallest angle. Then the other two angles are 2x and 3x. Their sum is ...
x +2x +3x = 180°
x = 30° . . . . . divide by 6
3x = 90° . . . . find the largest angle
The largest angle is 90°, a right angle. So, the triangle is a right-angled triangle.
SidesA triangle with angles of 30°, 60°, and 90° is a "special" right triangle. Its sides are in the ratio 1 : √3 : 2. That is, the shortest side is 1/2 the length of the longest side.
shortest side = 1/2(19 cm) = 9.5 cm
The length of the shortest side in the triangle is 9.5 cm.
__
Additional comment
In case you're not familiar with the side length ratios of the 30-60-90 special triangle, you can figure the side length from the Law of Sines. That tells you ...
a/sin(A) = b/sin(B) = c/sin(C)
where A, B, C are the angles; and a, b, c are their opposite sides.
The shortest side is opposite the smallest angle, so we have ...
a/sin(30°) = (19 cm)/sin(90°)
a = sin(30°)×(19 cm) = 1/2(19 cm) = 9.5 cm
The length of the shortest side is 9.5 cm.

A car rental agency advertised renting a car for $27.95 per day and $0.25 per mile. If Greg rents this car for 3 days, how many whole miles can he drive on a $150 budget?
Answers
Answer: 264.6 miles
Step-by-step explanation: Let's put the info we got from the problem into an equation. If the car is rented for three days, we need to multiply 27.95 by 3, which will give us 83.85. Now let's use the equation 150=83.85 + 0.25x, where x represents miles. Subtract 83.85 from both sides and we get 66.15 = 0.25x. Now divide both sides by 0.25 and we get x = 264.6.
Answer:
264 miles
Step-by-step explanation:
y = 27.95x + 0.25n where:
y = budget
x = days rented
n = miles driven
150 = 27.95(3) + 0.25n
150 = 83.85 + 0.25n
150 - 83. 85 = 0.25n
66.15 = 0.25n
66.15 / 0.25 = n
n = 264.6 miles
27.95(3) + 0.25(246.6) = $150

What is a quadratic equation?
In algebra, a quadratic equation is any equation that can be rearranged in standard form as
ax² + b*x + c = 0
The figures a, b, and c are the portions of the equation and may be distinguished by calling them, independently, the quadratic measure, the direct measure, and the constant or free term.
The values of x that satisfy the equation are called results of the equation, and the roots or bottoms of the expression on its left-hand side.
A quadratic equation has at most two solutions.
Given,
Initial height h(0) = 3 ft
Initial upward velocity v(0) = 36 ft/sec
Given ball height after 't' seconds is h(t) = 3 + 36t - 16r²
for h= 19 ft
19 = 3 + 36 t - 16 r²
16 r² - 36 t + 16 = 0
4 r² - 9 t + 4 = 0
Quadratic equation for ax² + b*x + c = 0 is x = -b ±√b² - 4ac / 2a
By using the above formula we get
t = 9 ± √9² - 4*4*4 / 2*4
t = 9 ± √81 - 64 / 8
t = 9 ± √17 / 8
t = 9 + √17 / 8 t = 9 - √17 / 8
t = 9 + 0.5 t = 9 - 0.5
t = 9.5 t = 8.5
