Question

in the following triangle, theta= 60. find the values of the angles B and B', which solve this ambiguous case

Answer 1

∠B + ∠B` = 180°
The Sine Law:
10 / sin B` = 9.2 / sin 60°
10 / sin B` = 9.2 / √3/2
sin B` = 0.94133
B` = sin^(-1) 0.94133
Answer:
C ) ∠B` = 109.73°, ∠B = 70.27°

Answer 2

B= 66.25 and B'= 113.75 on APEX
