how do you work out the length of a missing side on a 35 degree triangle?

for example the opposite side is 50.3 and the hypoteneuse is x opposite divided by hypoteneuse = 0.574 I AM SO CONFUSED!!

Sin(35) = Opposite side / Hypotenuse

Sin(35) = 50.3 / x take the sine of 35-degree angle.

0.573576...= 50.3 / x cross multiply

0.573576x = 50.3 divide both sides by 0.573576

x = 50.3 / 0.573576

x = 87.70 - The hypotenuse.
