In right triangle ABC with right angle C, the length of AB is 31 and the length of BC is 14. Find the measure of angle B. Round to the nearest tenth. 35.6°

63.2°

24.3°

26.8°

221,500 is the answer

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.
