Triangle x y z is shown. angle z w x is a right angle. an altitude is drawn from point w to point y on side z x to form a right angle. the length of w y is 4, the length of y x is a, the length of z y is 3, the length of z w is c, and the length of w x is b. what is the value of a? 5 units 5 and one-third units 6 and two-thirds units 7 units

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.

The answer would be 16
