Sine == opposite/hypotenuse = 2/sqrt(29)
Cosine == adjacent/hypotenuse = 5/sqrt(29)
Tangent == sine/cosine = opposite/adjacent = 2/5
theta = ASIN(2/sqrt(29)) = 20.4 degs.

Correction to oldprof's answer
theta = ASIN(2/sqrt(29)) = 21.8º.

This is a right triangle, yes?
The sin of the drawn θ is the length of the opposite side divided by the hypotenuse. What do you get?
Whats the "formula", the rule for a cos ? For a tan?
Your answers will follow.
