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.

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.

Of course its a right triangle; that's what the box in one corner means. Standard notation.
