Referring to the diagram, if c = 32 and theta is equal to 57.6 degrees, find the difference in the length of sides a and b. Another words determine the length of side a, determine the length of side b, and then subtract b from a (a  b). (For example if a = 10 and b = 2, then enter in 8.)

I have no idea what the diagram is.
