Question

Find the cosine of ∠V.

image of a right triangle that has the following values, Angle W, Angle V, Angle X, Line VW which has a length of 36, Line WX which has a length of 77, and Line VX which has a length of 85

Answer 1

Because 36^2 + 77^2 = 85^2, the hypotenuse is VX = 85 and the right angle is at W. For angle V the adjacent side is VW = 36, so

cos ∠V = adjacent/hypotenuse = 36/85 ≈ 0.4235.
