Write the coordinates of the vertices after a reflection across the x-axis -10
EC-9, 8) - E'
F(-9, 1) - F
G(-1, 1) – G'
H(-1, -8) – H

answer: 42

use a calculator to find that 845/73 = 11.575

the whole part of the answer is 11. multiply this by 73 to get 11*73 = 803.

subtract that result from 845 to get 845 - 803 = 42

it would rotate about 180 degrees.

43

step-by-step explanation:

not sure if this is supposed to be a trick question. 43 is the only one that makes any sense.
