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.

Question

cos θ = 0.9659 A = ? H = 20

Answer 1

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

Answer 2

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.
tan θ = ? O = 9 A = 15

Answer 3

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.
sin θ = 0.7071 O = 5 H = ?
