The sum of the angle measures of any triangle is
180
degrees. suppose that one angle in a triangle has a degree measure of
−10x2
and another has a degree measure of
+6x5
. write an expression for the degree measure of the third angle in the triangle.

Equation: x=180-[(-10×2)+(6x+5)]
Expression: 180-[(-10×2)+(6x+5)]

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.
