Explanation:
Let
x = the measure of angle 2y = the measure of angle 3The goal is to find y
For now, focus on the interior angles of triangle DEF. We have these three angles:
D = 90 (due to the square angle marker)E = angle 1 = 53F = angle 2 = xThose interior three angles add to 180. This is true for any triangle.
D+E+F = 180
90+53+x = 180
143+x = 180
x = 180-143
x = 37
angle 2 = 37 degrees
Now we can find y.
Focus on angles 2 and 3, which are x and y respectively. These two angles add to 180 because they form a straight line. Note: the triangle's angles summing to 180 is closely related to this idea where angle 2 and angle 3 are a linear pair.
So this means,
(angle2)+(angle3) = 180
x+y = 180
37+y = 180
y = 180-37
y = 143
angle 3 = 143 degrees
It's not a coincidence that we ended up with a previously calculated value of 143. It turns out that adding the remote interior angles D and E leads to the exterior angle EFG.
D+E = 90+53 = 143 = angle EFG
I'm using the remote interior angle theorem. Some textbooks may call this the exterior angle theorem. In my opinion, the phrasing "remote interior angle theorem" is more descriptive.

Which speed is the fastest?
A: 4 miles in 1/3
B: 1/3 mile in 4 hours
C: 1/2 mile in 3 hours
D: 2 miles in 1 hour
Answers
1/3 of a mile is 4 hours so a full mile would be 3 times 4 which is 12 so every 12 hours is 1 mile.
1/2 a mile takes 3 hours and 2 times 3 is 6 so every 6 hours is 1 mile.
A. 5 minutes per mile
B. 12 hours per mile
C. 6 hours per mile
The correct choice is A.

An estimate of the height, H metres, of a tall building can be found
using the formula
H = 3f + 15
where the building is f floors high.
A building is 85 floors high.
The real height of the building is 260m.
Work out the percentage error when estimating the height of this building using
the formula given.
Answers
Given that,
An estimate of the height, H metres, of a tall building can be found using the formula :
H = 3f + 15
where the building is f floors high.
f = 85
The real height of the building is 260 m.
To find,
The percentage error.
Solution,
We have,
H = 3f + 15
Put f = 85 in the above formula
H = 3(85) + 15
H = 270 m
Error,
[tex]E=\dfrac{270-260}{260}\times 100\\\\=3.84\%[/tex]
So, the required error is 3.84%.

Find the percent change if the original is $300 and the new cost is $1,100?
Answers
The percentage change from $300 to $1,100 is 266.67% increase
How?
1,100 - 300 ÷ 300 = 2.6667
2.6667 x 100 = 266.67%
^this is how you find the percent in change
(You could have just asked me to show my work instead of reporting me- that was a bit uncalled for)
Answer: $266.667% change
Step-by-step explanation:
(V2 - V3) (1100 - 300) 800
_______ x100 = ________ x 100 = ____ x 100= $2.66667% = $266.667%
V1 300 300 x 100 increase or change

two angles of an isosceles triangle are x and x+10.find two possible value of x
Answers
Recall two important facts:
- An isosceles triangle always has two identical angles
- The interior angles always add up to 180 degrees
Armed with this info, we can set up two different equations to solve for x, depending on which angle we treat as being one of the pair of identical angles.
If we assume that the identical angles are x, then:
180 = 2x + x + 10
170 = 3x
56[tex]\frac{2}{3}[/tex] = x
Alternately, we can assume that the identical angles are x+10. In this case:
180 = 2(x + 10) + x
180 = 2x + 20 + x
160 = 3x
53[tex]\frac{1}{3}[/tex] = x

What is the solution set of 6x2-24 = 0?
(-2.2
Answers
Answer:
x = { - 2, 2 }
Step-by-step explanation:
Given
6x² - 24 = 0 ( add 24 to both sides )
6x² = 24 ( divide both sides by 6 )
x² = 4 ( take the square root of both sides )
x = ± [tex]\sqrt{4}[/tex] = ± 2
solution set is { - 2, 2 }

Answers
Answer:
White roses - 7
Red roses - 17
Step-by-step explanation:
Set up proportional equations
White roses = x
Red roses = 3x - 4
Set equal to 24
x + 3x - 4 = 24
4x - 4 = 24
4x = 28
x = 7
x is white roses, so there are 7
Plug x value into red rose equation
3(7)-4
21-4 = 17 red roses

The price of a pair of shoes increases from $65 to $81. What is the percent increase to the
nearest percent?
Answers
Answer:
Percent increase = 25%
Step-by-step explanation:
Given that:
Old price of shoes = $65
New price of shoes = $81
Difference = 81 - 65
Difference = 16
Percent increase = [tex]\frac{Difference}{Old\ price}*100[/tex]
Percent increase = [tex]\frac{16}{65}*100[/tex]
Percent increase = 0.246 * 100
Percent increase = 24.6%
Rounding off to nearest whole number
Increase = 25%
Hence,
Percent increase = 25%
