Question

What are two possible measures of the angle below? On a coordinate plane, 2 rays form an angle. One ray sits on the x-axis in quadrant 1 and another sits on the y-axis between quadrants 3 and 4. –90° and 630° –45° and 630° –90° and 225° –45° and 225°

Answer 1

–90° and 630°

Explanation:

The answer above is correct.

Answer 2

–90° and 630°

Explanation:

The described angle will be -90° plus any integer multiple of 360°. Possible values for the angle are ...
