Suppose that AABC is a right triangle with ZC = 90, If AC = 6 and BC = 2, find the following quantities. sec B, CSC B, cot BFrom a point on ground level, you measure the angle of elevation to the top of a mountain to be 37 . Then you walk 190 m farther away from the mountain and find that the angle of elevation is now 20 . Find the height of the mountain. Suppose that AABC is a right triangle with 4': = 90D. If AC 2 5 and BC 2 3, find the following quantities. cos A, sin A, tan A. sec 8, cs: 8. cot B Suppose that AABC is a right triangle with AC = 90. If AC 2 l 8 and 3C = , find the following quantity. (tan A)(tan B)
