A and ∠B are complementary angles. If m∠A is 35LaTeX: ^\circ∘, what is the measure of B?

Since they are complementary, they both add up to 90 degrees. So, 90-35=55 degrees.

The measure of angle B is 55 degrees.

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.
