    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.
