Sin = Opposite/Hypotenuse, Cos = Adjacent/Hypotenuse, Tan = Opposite/Adjacent.
To remember, memorize as SOH, CAH, TOA.
Where A = Adjacent, H = Hypotenuse, O = Opposite.
Since we were given the opposite side and one angle & we're to find the hypotenuse, therefore, you use
Sin 63 = Opposite/Hypotenuse
Sin 63 = 125/Hyp.
:6¦1 Hyp = 125/Sin 63
