ΔABC is dilated by a factor of 4 to produce ΔA'B'C'.
A triangle ABC right angled at B with side lengths of 3, 4, 5 and angles of 90 degree, 37 degree and 53 degree.
What is A'C', the length of AC after the dilation? What is the measure of ∠A'?
A.
A'C' =
, m∠A' = 37°
B.
A'C' = 20, m∠A' = 37°
C.
A'C' = 20, m∠A' = 148°
D.
A'C' = 12, m∠A' = 53°
