how to find sine angle if the givens are opposite and adjacent sides?

i find this very confusing, i already did the sine formulas and the rest but still can't get it right

sin = opposite / hypotenuse = 172/hypotenuse

use pythagorean theorem to calculate the hypotenuse THEN use that result to calculate the sin

HYPOTENUSE = N = sqrt( 32^2 + 172^2) ..... need more help??

@ElectricPavlov i did the exact thing you said, the hypotenuse was 174.95 (i rounded it off) so to get the sin angle i did

opposite/174.95 = 0.98, then in sin degree form it showed 78.52 but still wrong. did i put something wrong or calculate it wrong??

i'm so confused
