Find the reference angle for 12pi/5

-72°

Step-by-step explanation:

To convert from degrees to radians, multiply the degrees by .

To convert from radians to degrees, multiply the radians by .

Right now you're in radians, so multiply it by .

=.

Now we need to find the reference angle for 432, meaning we need to find the closest angle to it that is divisible by 180°, and find the difference

432° is between 180°*2=360° and 180°*3=540°.

432-360=72°

540-432=108°

432° is 72° away from 360° and 108° away from 540°, so 360° is closer.

If you draw 432° on a circle, you will go 360° and end up 72° into the fourth quadrant, meaning the angle is negative.

lol.

it's ok we all do this sometimes.
