lol i suck in trig also sorries

anonymous · Answer

Not tan. We know theta and which side do we know, O, H or A?

anonymous · Answer

adjacent?

i mean a

hero · Answer

cos(17) = 18.8/RS

RS = 18.8/cos(17)

anonymous · Answer

Perfect. We know adjacent since it is the side that touches the angle. So the trig ratio we'll use is cosine.
