For the right triangle ABC shown in Figure 2 below, find the values of all six trigonometric functions of the acute angles A and B. Figure 2: A Given Right Triangle. Show Solution. The hypotenuse of ABC has length 5. For angle A, the opposite side BC has length 3 and the adjacent side AC has length 4. Thus:For this type of problem, use the equation: cosine (x) = adjacent ÷ hypotenuse. If the length of the adjacent side is 1.666 and the length of the hypotenuse is 2.0, divide 1.666 by 2, which is equal to 0.833. So, cosine (x) = 0.833 or x = cosine -1 (0.833). Plug 0.833 into your graphing calculator and press cosine -1.How to Solve Trig Ratios of General Angles; Step by step guide to finding missing sides and angles of a Right Triangle.
