LAST PART. OTHER PARTS POSTED ON MY ACCOUNT PLEASE HELP DUE TODAY Reflection:
Pick one of the math concepts you listed in the pre-write. What is one of the most common mistake students make in this situation? Why do they make the mistake? What suggestion would you give to future students in order to avoid the mistake? Please write at least 4-5 complete sentences.

This polygon has 4 sides
180(4-2) = 180(2) = 360 degree
80+90+2x + 3x = 360
170+5x = 360
5x = 190
x= 38
measure of angle t is 2(38)= 76
the answer is c. trust me
hope this !

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.
