Question

Find an angle in the normal range for (0° to 360°, or 0 to 2pi radians) whose terminal side points in the same direction as the terminal side of an angle measuring -108°

​

Answer 1

C

Explanation:

Our angle is -108 degrees, but because angles on the unit circle are always periodic and repeat every 2π or 360°, that means if we add a certain multiple of 360 to -108, we should get an angle with the terminal side pointing in the same direction.

Let's add 360 to -108:

-108 + 360 = 252°

Thus, the answer is C.

Answer 2

c. 252°

Explanation:

To get an angle between 0 and 360, just keep on adding/subtraction 360° to the given angle till you find an angle in the required interval

-108 + 360 = 252°
