We have a angle of 74° Adjacent with 124 Calculate the length of the opposite side
We can use the tangent for this
tan(74) = opposite / 124 re-arrange
124 tan(74) = opposite = about 432.4
Adding to Cphill's answer
rememeber 'SOHCAHTOA' which is a memory mnemonic for
Sine = Opposite/Hypoteneuse
Cosine = Adjacent/Hypoteneuse
Tangent = Opposite/Adjacent
