Question 847513
Here is what your graph should look like. Perhaps try to put in a TI-83/84 or you can use wolframalpha like I did.

Anyway, we need the answer that is between 0<x<360

Notice that all these answers are in radians, so convert them to degrees.

x = 20 degrees, 100 degrees, 140 degrees, 220 degrees, 260 degrees
