Since they share the same angle measurement, and 4 is smaller than 158 degrees, you subtract 158 from 180 and angle 4 = 22 degrees
Answer:
7) B, C
8) D
Step-by-Step-Explanation:
The first thing you need to solve for is the the parenthesis
the second one simplifies to x ≤ -7
36(3.14) = 4/3 x 3.14 x r^3
113.04 = 4.187(r^3)
113.04/4.187 = r^3
26.997 = r^3
3√26.997 = r
r = ~3
Check: 3^3(

)(4/3) = 27(3.14)(4/3) = 113.04
