=0.06

Solution:

Given, an angle in standard position measures −5π/3 radians.  

We need to find in which quadrant does the terminal side of this angle lie.

First let us convert -5π/3 radians into degrees.

= -5 x 60 degrees = -300 degrees

Here, -300 represents that terminal side is rotating in anti clock wise direction. So now to find the positive angle.

Positive angle = 360 – 300 = 60 degrees

We know that, 0 degrees < 60 degrees < 90 degrees

Hence, the terminal side of this angle lies in the first quadrant.
