For AABC, ZA = 3x, ZB = 2x - 3, and ZC = x + 3. If AABC undergoes a dilation by a scale factor of 2 to create AA'B'C'
with ZA' = 2x + 30, ZB' = x + 27, and ZC = x + 18, which confirms that AABC~AA'B'C by the AA criterion?
A)
ZA = ZA' = 75° and ZB = ZB' = 47°
ZA = ZA' = 60° and ZB = ZB' = 37°
ZB = ZB' = 57° and ZC = ZC' = 33°
= ZA' = 105º and ZC = ZC' = 38°

Asquare is dilated by a scale factor of 1.25 to create a new square. how does the area of the new square compare with the area of the original square? a)the area of the new square is 1.25 times the area of the original square. b)the area of the new square is 2.50 times the area of the original square. c)the area of the new square is 1.252 times the area of the original square. d)the area of the new square is 1.253 times the area of the original square.
