One of the beauties of these trigonometric functions is that you can find the measure of an acute angle of a right triangle if you know two of the sides of the triangle. Using Trigonometric Functions to Find a Missing Angle WebLet's find angle A first: cos (A) = (b 2 + c 2 − a 2) / 2bc cos (A) = (6 2 + 7 2 − 8 2) / (2×6×7) cos (A) = (36 + 49 − 64) / 84 cos (A) = 0.25 A = cos -1 (0.25) A = 75.5224...° A = 75.5° to one decimal place. Next we find another side. We use the Law of Cosines again, this time for angle B: cos (B) = (c 2 + a 2 − b 2 )/2ca
