Card 1 of 20

Which side forms an opposite pair with angle BBB?

A

b=9sin⁡76∘sin⁡42∘b=\frac{9\sin76^\circ}{\sin42^\circ}b=sin42∘9sin76∘​

B

When two sides and a non-included angle are known.

C

Side bbb.

D

If inverse sine gives an acute angle θ\thetaθ, the possible second angle is 180∘−θ\boxed{180^\circ-\theta}180∘−θ​.
