Question

What is the value of b?

A. 100

B. 90

C. 80

Answer 1

Answer: the answer is C. 80°

Explanation:

= 360 - 110 - 90

=160°

b=1/2 (160)

b=80°

Answer 2

C. 80 degrees

Explanation:

The measure of the given arcs are 90 and 110.

Subtract those values from 360

= 360 - 90 -110

= 160

The angle b is half of 160 degrees, the measure of the arc that intercepts it.

Therefore, it measures 80 degrees.

Hope this helps :)
