Things to remember:

Sin = Opposite / Hypotenuse

Cos = Adjacent / Hypotenuse

Tan = Opposite / Adjacent

Whatever 2 terms you have in your equation are the ones you will use to determine Sin/Cos/Tan. For example, in question 21, the “X” was adjacent to your given angle (74°). The hypotenuse was 12, so you would use Cos since your two terms are Adjacent / Hypotenuse.

Also remember, the hypotenuse is the side opposite of the 90° angle.

The opposite side is the side opposite of the angle given (Not 90°).

The adjacent side is the side adjacent to the angle given (Also not 90°).

Arhombus is a quadrilateral.

Just divide the x axis (the top) by 2 or multiply the y axis (the bottom) by 2
