Question

In which quadrant is the terminal side of 270 degrees located?

Answer 1

`" "`
Please read the explanation.

Explanation:

`" "`
A `color(blue)("Quadrantal Angle"` is any angle in standard position with its terminal side on the x-axis or the y-axis.

Observe the angle `color(blue)(270^@` on a Cartesian Coordinate Plane:

The terminal side of the angle is on the y-axis.

Hence, that angle `color(red)(270^@` is a Quadrantal Angle.

Hope it helps.
