∠A and \angle B∠B are complementary angles. If m\angle A=(x+28)^{\circ}∠A=(x+28) ∘ and m\angle B=(4x-8)^{\circ}∠B=(4x−8) ∘ , then find the measure of \angle A∠A.

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 formula of a slope:

we have the points (-2, 7) and (2, 3). substitute:

answer: the slope is equal -1.

C. because 6÷3=2 so 3 is half of six so 3/6
