When you put these two angles together, they make a straight angle: In the right-angled triangle given, the measure of each of the acute angles in the given diagram are:. When the terminal side is in the fourth quadrant (angles from 270 to 360), our reference angle is 360 minus our given angle. Therefore, the sets of ratios depend only on the measure of the acute angle, not the size of the triangle. Here are some examples: If the terminal arm is in quadrant 2, do 180^@ minus the principle angle to find the related Learning math takes practice, lots of practice. The reciprocal of cosine is the secant: sec(x), sometimes written as secant(x), which gives the ratio of the length of the hypotenuse to the length of the side opposite to the angle.
