Question

Find the value of b.

Answer 1

C.

Explanation:

We have to halve the difference of the intercepted arcs.

I knew the bigger arc's measurement was 180 degrees because it's central angle is 180 degrees.

So you have to perform the following operations:

`(1)/(2)(180-35)`

`(1)/(2)(145)`

`(145)/(2)`

`72.5`
