Coterminal angle between 0 degrees and 360 degrees if coterminal angle is -450

Answers

Using equivalent angles, it is found that the coterminal angle is of 270º.

Equivalent Angles:In the trigonometric circle, ranging from 0 to 360º,  each angle has an equivalent on the each quadrant.A negative angle is given by the trigonometric circle in clock-wise rotation, hence, to convert to positive, we keep adding 360º.

In this problem:

The angle is of -450º.-450 + 360 = -90º, which means that the original angle gave more than one lap of the circle.Adding again, -90 + 360 = 270º, which is the coterminal angle.
