Question

Find an angle in the normal range (0 degrees to 360 degrees, or 0 to 2pi radians) whose terminal side points in the same direction as the terminal side of an angle measuring -11pi/3.

​

Answer 1

A

Explanation:

We see that the angle is -11
`\pi`/3, which means that when drawing this angle on the graph, we need to move clockwise from 0 (see the drawing).

We see that this angle is actually the exact same as an angle in the first quadrant. This angle is
`\pi`/3.

Thus, the answer is A.

Hope this helps!

Answer 2

a) pi/3

Explanation:

-11pi/3 + 4pi

(-11+12)pi/3

pi/3
