Question

what is the measure of ∅?

A. 2.5 π radians
B. 2.5 radians
C. 4 radians
D. 5 radians​

Answer 1

Answer:

C. 4 radians

Step-by-step explanation:

$20=\frac{\pi (Ctrl.Angle)(5)}{180}$

Ctrl Angle = ∅

∅ = $\frac{(20)(180)}{5\pi } =\frac{3600}{5\pi } =\frac{720}{\pi }$

in radians:

∅ = $\frac{720}{180} =4$

Hope this helps
