If ∠R is given and the values of r and q are given, then explain whether the Law of Sines or the Law of Cosines should be used to solve for ∠Q. Law of Sines, two sides and an opposite angle are known
Law of Sines, two angles and the included side are known
Law of Cosines, all sides are known
Law of Cosines, two sides and the included angle are known

Iwould like to think so. what’s the question you need with?

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.
