Question

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

Answer 1

The given angle is

$\theta=-\frac{100}{\pi}$

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

$\theta=-\frac{100}{180}=-\frac{50}{90}=-\frac{5}{9}=-0.56$

The given angle is placed on the first quadrant.

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