Using the addition or subtraction formulas for sine: addition formula sin(s + t) = sin s cos t + cos s sin t or the subtraction formula: sin(s + t) = sin s cos t - cos s sin t.

What is the exact value of the expression sin(285 degrees)?

Please show steps and give explanation so I can know how to do the other problems. I am mostly confused how to split up the number into manageable numbers that I know the specific value for. Like 30 degrees or 40 degrees.
