The required vertex angle will be 100° in the given figure.
What is an Isosceles Triangle?An Isosceles Triangle is defined as a triangle with two sides of equal length is an isosceles triangle.
The triangle given in the figure is an Isosceles triangle.
It is given that side AB is equal to side AC.
So ∠B = ∠C = 40°
Now we know that the sum of angles of a triangle is equal to 180°. So here in this triangle ABC. These are the sum of these three angles will be equal to 180.
As per the given figure,
∠A + ∠B +∠C = 180°
∵ ∠B = ∠C = 40°
∠A + 40° +40° = 180°
∠A + 80° = 180°
∠A = 180° - 80°
∠A = 100°
Therefore, the required vertex angle will be 100° in the given figure.

Answer:
27 minutes.
Step-by-step explanation:
R = k/t
Substituting given info
600 = k/45
k = 45 * 600 = 27000
So the relation is S = 27000/t
So if R = 1000
1000 = 27000/t
t = 27000/ 1000
t = 27.
An angle measures 24º more than the measure of its complementary angle. What is the
measure of each angle?
What are the two angles please hurry
Answer:
33, 57
(not 100% sure this is correct)
Step-by-step explanation:
90= x +(24 +x)
(drag 90, plus the x's and drag the 24)
90 = 2x + 24
(Subtract 24 from 24 and 90 from 24)
66 = 2x
(Divide both by two)
33 = x
(now use x and plus it by 24)
24 + x = 57
Addie increased the amount of chocolate chips she used for the cookie recipe by 45%. The original recipe used 28 ounces of chocolate chips. How many ounces of chocolate chips will Addie use for her recipe?
Answer:
10%of 28=2.8
40%=2.8 ×4=11.2
5%(half of 10%)=1.4
then you add 40%and 5% which is 11.2+1.4=12.6
(on a calculator you can work percentage by doing 45 percentage button×the amount)
then you add 28 ounces(original)+(increase) which is 12.6=
40.6
Addie will use 40.6 ounces of chocolate for her recipe

Answer: x = 59°, y = 114°.
Step-by-step explanation:
The sum of the opposite angles of a quadrilateral in a circle is 180°.
y = 180° - 121° = 59°
The two angles being adjacent makes a total angle of 180° on the straight line.
x = 180° - (180°-114°) = 180° - 66° = 114°

Elsie bought a video game for 85$. if the store charges 170% of its cost for the game, how much is the store's profit?
Answer: $59.5
170/100 * 85 = 144.5
144.5 - 85 = 59.5
If that is wrong my next guess is $144.50

B: The area of a rectangular window is 7007 cm If the width of the window is 77 cm, what is his length?
Answer:
A) the width is 89
B) if area is 7007, the length is 91
Step-by-step explanation:
Answer:
A: 89 m
B: 91 m
Step-by-step explanation:
A: P=2(L+W)
P=2L+2W
P=2(99)+2W
2W=376-198=178
W=178/2=89m
B: A=L×W
7007=L×77
L=7007/77=91
L=9l m

A sweater that is regularly priced at $25 is on sale for 25% off.
What is the amount of the discount?
What is the sale price?
What is the total price of the sweater including the 6.5% sales tax?
need help now plz
Answer:
Discount = 6.25
Sale Price = 18.75
6.5% tax = 1.21875
Final price = 19.96875 = 19.97
Step-by-step explanation:
25 x .25 = discount
25 - 6.25 = sale price
18.75 × 0.065 = tax
18.75 + 1.21875 = final price

If there are 4 apples for every 5 oranges, and there are 16 apples, how many fruits are there altogether?
Answer:
36
Step-by-step explanation:
4:5
16:n
16÷4=4
4×5=20
16:20
16+20=36
Answer:
36 fruits (I'm not sure, but I think it's correct)
Step-by-step explanation:
4 apples = 5 oranges
16 apples = ? oranges
4 x ? = 16
4 x 4 = 16
5 x 4 = 20
4 apples = 5 oranges
16 apples = 20 oranges
16 + 20 = 36 fruits

PLS PLS HELP!!!! Write and solve an inequality to find the possible values or x if the area of the
rectangle is < 56 feet squared.
2 ft
(3x + 4) ft
Answer:
width=2 ft, length=(3x+4)ft
Area of Rectangle=width x length
=2ft . (3x+4)ft
=6x+8 ft sq
Area of Rectangle <56 ft sq
6x+8 ft sq <56 ft sq
6x < 56 ft sq - 8 ft sq
6x < 48 ft sq Substeracting 8 on both sides
6x/6 < 48 ft sq/6 Dividing by 6 on both sides
x < 8 ft sq

The two triangles are similar and therefore we can set up a proportion
9/(9 + 72) = (3x - 20)/(3x - 20 + 56) Combine like terms on the right
9/(81) = (3x - 20)/(3x + 36) Cross multiply
9(3x + 36) = 81 (3x - 20) Remove the brackets.
27x + 324 +1620 = 243x Add 1620 to both sides
27x + 324 + 1620 = 243x Subtract 27x from both
1944 = 216x divide both sides by 216
x = 9
If you feel comfortable canceling the size of the numbers can be reduced.
9/81 = 1/9
1/9 = (3x - 20)/(3x + 36)
3x + 36 = 9(3x - 20)
3x + 36 = 27x - 180
36 + 180 = 24x
216 = 24x
216/24 = x
x = 9
There is another cancelation possible, but this is simple enough.

Vector B has x, y, and z components of 3, 7.2,
and 4.5 units, respectively.
Calculate the magnitude of B
Answer:
[tex]\approx 9.0\:\mathrm{units}[/tex]
Step-by-step explanation:
The magnitude of 3D vector [tex]\vec{v}[/tex] can be given by the following:
[tex]| \overline{v}| =\sqrt{{v_x}^2+{v_y}^2+{v_z}^2}[/tex]
Plugging in given values, we have:
[tex]| \overline{v}|=\sqrt{3^2+7.2^2+4.5^2},\\| \overline{v}| \approx \fbox{$9.0\:\mathrm{units}$}[/tex].

What expression is equivalent to
15n + 20r
Answer: 5(3n+4r)
Step-by-step explanation:You need to find the gcf/factor .So the gcf of 15 and 20 is 5.So know that you know the gcf ,you divide 15n by 5 which gives you 3n and divide 20r by5 which gives you 4r.Now the last thing you do is,take the GCF which is 5 and place a Parentheses and take 3n and 4r and add them together.
So you get 5(3n+4r) as your expression that is equivalent to 15n + 20r .
