Answer:
See below.
Step-by-step explanation:
Use the compound angle identity:
sin(A - B) = sinA cosB - cos A sin B.
Plugging in the given angles:
A = 360 and B = O so:
sin (360 - O) = sin 360 cos O - cos 360 sin O
sin 360 = 0 and cos 360 = 1 therefore we have
0 * cos O - 1 * sin O
= 0 - sin O
= -sin O.
