Question

Need help with both questions

Answer 1

quad 1

quad 4

Explanation:

left problem

405 degrees is going to go anti clockwise. It will eat up 360 of those degrees rotating once

405 - 360 = 45 degrees.

405 is equivalent to 45 degrees and is in Quad 1.

right problem

- 405 degrees is moving clockwise in when 1 arm is the + x axis. -360 is eaten up just making 1 rotation. You have - 45 degrees left over

- 45 degrees is in quad 4 when moving clockwise.

Answer 2

1. Quadrant I
2. Quadrant IV

Explanation:

Angles are measured counterclockwise from the positive x-axis, so after 360°, the terminal side starts again in Quadrant I.

1. Since the angle is between 360° and 450°, its terminal side is in Quadrant I.

2. When an angle represents a clockwise rotation from the positive x-axis, it is given a negative angle measure. After -360° the terminal side starts again in Quadrant IV. Since the angle is between -360° and -450°, its terminal side is in Quadrant IV.
