Construct an inscribed circle in ΔPQR by finding the the incenter of the triangle

Ithink the answer is b i hope it my friend message me if i’m wrong and i’ll change my answer and fix it for you

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.

Ibelieve the answer is c i worked it out three times but if my answer is wrong someone correct me

Where’s the picture or data?
