Which composition of similarity transformations maps polygon ABCD to polygon A'B'C'D'?

x + 4/7

step-by-step explanation:

use cymath

11.2

step-by-step explanation:

when doing tangent the tangent of the angle is equal to the opposite side from the angle over the adjacent side to the angle.

tan43 = x / 12

move 12 over by multiplying each side by 12

12tan43 = x

x = about 11.2

i'm assuming that it's c.)   volcanoes built the mountains and earthquakes tore them down.
