Question #07942

Answer 1

`5/4pi`

Explanation:

Coterminal angles are two angles that are drawn in the standard position (so their initial sides are on the positive x-axis) and have the same terminal side like 110° and -250°.

Another way to describe coterminal angles is that they are two angles in the standard position and one angle is a multiple of 360 degrees larger or smaller than the other. That is, if angle A has a measure of M degrees, then angle B is co-terminal if it measures M +/- 360n, where n=0,1,2,3, ... (for degrees)

For radians the angle B is co-terminal if it measures `M "+/-" (2pi)n`, where n=0,1,2,3, ...

`-3/4 pi + 2pi = 5/4pi`
