Question

Find the measure of each missing θ. Round to tenths

Answer 1

Explanation:

Here is where to start

Remember for RIGHT triangles:

S-O-H-C-A-H-T-O-A ???

First one Sin Φ = Opposite/Hypotenuse = 20 /29

Φ = arcsin (20/29)

Second One tan Φ = 12/15

Φ = arctan(12/15)

Last one cos Φ = 377/512
