Step-by-step explanation:
Answer:
6.3
Step-by-step explanation: Divide 7 by 10 and get .7 then you would multiply that by 9 and youll get 6.3
∠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°
