Use a table of trigonometric values to find the angle θ in the right triangle in the following problem. Round to the nearest degree, if necessary.

cos θ = 0.9659 A = ? H = 20

I pitched those tables over 25 years ago, just about every cheap calculator can do trig.

cos Ø = .9659

Ø = 15°

Since I can't see your diagram , you will have to decide whether to use the sine or the cosine of 15° to find the rest
