i need help with using sine in SOH CAH TOA. the opposite angle is 5 in this case, and i need to find hyp. the angle is 36, so do i do:
Sin 36= 5 / Hyp?
For sine 36 i got 0.5877853, but then what do i need to multiply it with to find the Hyp? do i multiply it by 5? im so confused please help!!

Sine 36 = Opp. Side / Hyp.
Sine 36 = 5 / Hyp.
Hyp. = 5 / Sine 36
Hyp. = 5 / 0.587785252
Hyp. = 8.506508084 or 8.51

SOH CAH TOA doesn't work on angles. It is used when you know the lengths of at least two sides. Then, you use the Pathagorean Theorem to find the third side.

From your story:-
sin 36° = 5 / h
h sin 36° = 5
h = 5 / sin 36°
h = 8.51

using the numbers you give
.5877=5/hyp
multiply through by hype to get
hyp*.5877=5 and solve
hyp = 5/.5877=8.5
