Answer:
x = 40°
Step-by-step explanation:
Two sides are the same length, so the angles opposite them are the same size.
The sum of the angles = 180°. One angle is 100°, so the sum of the remaining two angles is 80°.
Since the remaining two angles are congruent, each is 40°.

Answers
Answer:
x + 5
Step-by-step explanation:
A = LW
W = A/L
W = (x^2 + 16x + 55)/(x + 11)
W = [(x + 11)(x + 5)]/(x + 11)

The pie chart below represents the vehicle types owned by families. If the total number of people surveyed is 1000, approximately how many own a van?
Answers
Answer:
500 families
Step-by-step explanation:
We want to estimate the size of the dark blue section of the chart. The chart looks like the left of the pie chart is split evenly with the dark blue section. So we estimate that each of those must represent 12 or 50% of the total number of families. Therefore,
0.50⋅1000=500
About 500 families own a van.

r delta math
In this figure, angles R and S are complementary. Find the measure of angle S.
Answers
Answer:
S = 28 degrees
Step-by-step explanation:
The given angles are R = 62 and Q = 90 since there's the square showing its a right angle.
It says that R and S are complimentary which means together their total is 90 degrees. So there are two ways to do this;
R + S = 90
62 + S = 90
-62 -62
S = 28
OR
R + S + Q = 180
62 + S + 90 = 180
152 + S = 180
-152 -152
S= 28
Answer:
The answer I got was 28°
Step-by-step explanation:
1. Triangles add up to 180°
2. The "square" in the triangle means that angle is equal to 90°
3. Add the 90° angle with the 62° angle
4. Subtract the answer (152°) from the total (180°)
5. The answer is 28°
