Analyze the diagram below and complete the instructions that follow. find the area of qrs. a. 202.9 square units b. 215 square units c. 238.7 square units d. 273 square units

Answer-

The area of QRS is 238.7 sq units.

Solution-

According to properties of supplementary angles,

So,

As the sum of measurement of all the angles in a triangle is 180, so

Then the area of the triangle will be,

i leave the calculator work to you.

7. diameter 4 miles, circumference 4π miles

8. radius 0.2 miles, circumference 0.4π miles

[this is a bad problem because the actual radius of a car on the track is less than 0.2 miles so the answer is less than 0.4π miles]

9. radius 6 feet, circumference 12π feet

10. diameter 14 cm, circumference 14π cm

11. diameter 4.8 feet, circumference 4.8π feet

1. sometimes

2. never true

3. sometimes

step-by-step explanation:

these are pretty self explanatory if you know what supp right and com angles are
