If you are given right triangle ABC with angle B being the r

If you are given right triangle ABC, with angle B being the right angle, and you are given that cos A = 40/41, then find: Sin C =_____ Cos C = _____ tan A = _____ sin A = _______

Solution

A = 12.68

B = 90

C = 90 - 12.68 = 77.32

cos A = 40/41 = Base/Hypt

Perp = sqrt[41^2 - 40^2] = 9

sinC = 40/41

cosC = 9/41

tan A = 9/40

sin A = 9/41
