    In relation to the angle x, what sides do you know: hypotenuse, adjacent, opposite. Choose.

    Do you understand that the hypotenuse is always the longest sides in a right triangle and that it is opposite the right angle?

    dang, buddy, the triangle only has 3 sides. If it's not the hypotenuse, what is left?

    Which is the adjacent side: 11 or 33? Remember adjacent means "next to"

    Now, you know the adjacent side and the opposite side, what trig function does that make you think of?
