Question

Need help with finding A and B

Answer 1

Hello!

First of all, let's find A. This is the opposite and hypotenuse we will be dealing with. Therefore, we will use the sin.

sin30= 0.5

This gives us the equation below.

a/12=0.5

a=6

Now we find b. This is the adjacent and hypotenuse. Therefore, we will use the cosine.

cos30≈0.87

This gives us the equation below.

b/12=0.87

b=10.44

I hope this helps!
