Step-by-step explanation:

Recall the half-angle identity:

So in order to find

, we only need to know the value of

. But there are two possible values. To decide which to take, we use the given information: we know that

lies in quadrant III, which means

, so

, which places

in quadrant II. In this quadrant, the sine of angle is positive, and so


is an angle of a ray whose terminal point,

lies on the circle

. The

-coordinate is all we need to know in order to find that

. So,
