The two polygons are similar. Write a proportion and solve for x. I just need help with 11 and 13 ​

When two lines intersect, they form two pairs of equal angles, which, taking one of each, add up to 180°. (jargon: angles forming a straight line   show more

Ask google i believe they can you with that question

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.
