Question

PLEASE HELP!!! Given angle circled dash=208° and a right triangle inscribed within a circle of radius 5, what is the value of x of the corresponding coordinate?

-2.34
-4.41
2.34
4.41

Answer 1

-4.41

Explanation:

208° is a 3rd-quadrant angle, so its x-coordinate will be negative. Your calculator can tell you that 5 times the cosine of this angle is -4.41, or you can refer to a diagram.
