Question

BRAINLIEST ASAP! PLEASE HELP ME :)

Answer 1

$\sin(360 - \theta) = -\sin(\theta)\\\\\sin(360)\cos(\theta)-\cos(360)\sin(\theta) = -\sin(\theta)\\\\0*\cos(\theta)-1*\sin(\theta) = -\sin(\theta)\\\\-\sin(\theta) = -\sin(\theta)$

The identity has been confirmed. Note how I only altered the left hand side to transform it into the right hand side. In the second line, I used the identity $\sin(x-y) = \sin(x)\cos(y)-\cos(x)\sin(y)$
