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.

f(x) is the value of the function. b is the value of the function when x equals zero or the y-coordinate of the point where the line crosses the y-axis in the coordinate plane.

y < -3

step-by-step explanation:

-3y - 2 > 7

-3y -2 + 2 > 7+2

-3y > 9

-3y/-3 < 9/-3   (change the inequality sign when multiplying or dividing by a negative number)

y < -3
