With this information, what trig function (cos, sin, or tan) will you use to solve for side XY? Write an equation using A to represent your known angle, ZY to represent your known side, and x to represent the unknown side XY. The final step is once you know the length of XY, adding to XY the additional height.

sin x, cos x, tan x, cot x, csc x, sec x. The transformations of the tangent, cotangent, secant, and cosecant functions work the same way as the transformations of the sine and cosine. The only difference is the period of the tangent and cotangent. The period of functions y = sin kθ, y = cos kθ, y = csc kθ, and y = sec kθ is 2π/k.
