Answer 5

So what would you use sine, cosine or tangent to solve?

Answer 6

Would you use Sine? @nelsonjedi

Answer 7

Why sine?

Answer 8

Because you use Sine when it's a right triangle and only need to know one side of the triangle and its opposite angle when using the sine formula? @nelsonjedi

Answer 9

I'm thinking its 6 sin 32, so B.

Answer 10

So sin 32 = BC / 6 correct

Answer 11

So Sin 32 x 6 = BC very good
