The mascot holds the end of a kite string 4 feet above the ground. The string makes an angle of elevation of 38˚. If 55 feet of string are let out, how high off the ground is the kite?

The correct answer is addition

Period is the time it takes for one “cycle” to complete. in the parent sine function, period is 2*pi since sin(0) = 0, sin(pi/2) = 1, sin(pi) = 0, sin(3pi/2) = -1, and sin(2pi) = 0. at that point, the sequence repeats itself. i’m not sure if your graph is similar to the sine function since you didn’t provide a picture, but you can find the period by looking at a graph.
