Pleeeaaassseee ! for δabc, ∠a = 4x - 4, ∠b = 6x - 1, and ∠c = 8x - 13. if δabc undergoes a dilation by a scale factor of 2 to create δa'b'c' with ∠a' = 51 - x, ∠b' = 4x + 21, and ∠c' = 6x + 9, which confirms that δabc∼δa'b'c by the aa criterion? a) ∠a = ∠a' = 44° and ∠b = ∠b' = 71° b) ∠a = ∠a' = 36° and ∠c = ∠c' = 67° c) ∠b = ∠b' = 59° and ∠c = ∠c' = 67° d) ∠b = ∠b' = 65° and ∠c = ∠c' = 75°

The angle in the dilated figure is the same as the original angle in each case, a fact that should be confirmed by the way the answer choices are shown.

∠A = ∠A'

... 4x -4 = 51 -x

... 5x = 55

... x = 11

∠A = 4·11 -4 = 40 . . . . . . doesn't match any offered choice

___

∠B = ∠B'

... 6x -1 = 4x +21

... 2x = 22

... x = 11

... ∠B = 6·11 -1

... ∠B = ∠B' = 65 . . . . . matches selection D)

∠C = ∠C'

... 8x -13 = 6x +9

... 2x = 22

... x = 11

... ∠C = 6·11 +9 = 75

... ∠C = ∠C' = 75 . . . . . matches selection D)

step-by-step explanation:

when a number is between two straight lines it means the absolute value.

to find absolute value you need to know how many numbers is that number away from 0.

when finding absolute value the number will always come out positive

so absolute value of -3 is 3

absolute value of 3/2 is 3/2

absolute value of -2 is 2

absolute value of 3.5 is 3.5

absolute value of -1 is 1

now put these numbers in order:

a)   |-1|, |3/2|, |-2|, |-3|, |3.5|
