Question

In the following triangle, find the values of the angles Band B, which are the best approximations to the solutions to this ambiguous case?​

Answer 1

B. B = 70.5° or B' = 109.5°

Explanation:

(sin 45°)/13.5 = (sin B)/18

sin B = (18 * sin 45°)/13.5

sin B = 0.9428

B = sin^-1 0.9428

B = 70.5°

B' = 180° - 70.5°

B' = 109.5°
