Question

In which quadrant, or on which axis, does the terminal side of angle (- 100straight pi) lie?

Answer 1

The given angle is

`\theta=-(100)/(\pi)`

First, we have to transform this angle into degrees. We know pi=180°, so

`\theta=-(100)/(180)=-(50)/(90)=-(5)/(9)=-0.56`

The given angle is placed on the first quadrant.

Assuming that the angle is starting on the positive x-axis.
