Question

A similarity transformation maps ∆ABC to ∆JKL. The measure of ∠A of preimage ∆ABC is 105°. The scale factor of the dilation in the similarity transformation is 1.5. If ∠A in the preimage corresponds to ∠J in the image, what is m∠J? A. 70° B. 140° C. 105° D. 35°

Answer 1

Answer:

Option C. $m<J=105\°$

Step-by-step explanation:

we know that

If two figures are similar, then the ratios of its corresponding sides is equal and its corresponding angles are congruent

so

m<A=m<J

m<B=m<K

m<C=m<L

therefore

The measure of angle J is the same that the measure of angle A

$m<J=105\°$

Answer 2

Answer:

The answer would be option C. 105
