The value of a is (c) 86
<h3>How to solve for a?</h3>
The given parameter is:
Angle C = 86
By vertical angle theorem, we have:
Angle A = Angle C = 86
This implies that:
Angle A = 86
The arc A subtends angle A
This means that:
Arc A = 86
Hence, the value of a is (c) 86

180° = π radian
1° = π/180 radian
∵ 145° = π/180 × 145
= 36π/29 radian
