sine (28) = opposite / hypotenuse =
0.46947 = opposite / 28
opposite = 0.46947 * 28
opposite side = 13.14516

cosine (28) = adjacent / hypotenuse =
0.88295 = adjacent / 28
adjacent = 28 * .88295
adjacent side = 24.7226

Double Check

 13.14516^2 + 24.7226^2 = 28^2

172.7952314256  + 611.20695076 = 784

784.0021821856 = 784
