Given the figure below, find the values of x and z

m∠z = 99°

x = 12

General Formulas and Concepts:

Geometry

Step-by-step explanation:

Step 1: Find m∠z

99° and z° are Vertical Angles.

m∠z = 99°

Step 2: Find x

m∠z and (7x - 3) must add up to 180° since they are Supplementary.

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

these sign is used to tell weather the number is greater or less than the number   <   or >     but this sign means its equal =
