Triangle abc is similar to triangle def. which statement is true about the two triangles? a. angle a and c are congruent b. angles a and d are congruent c. angles b and e are proportional d. angles c and d are propotional

B. Angles A and D are congruent

Step-by-step explanation:

We know that if two triangles are similar then its corresponding angles are congruent and corresponding sides are proportional.

Hence, If ΔABC is similar to ΔDEF, then

∠A≅∠D , ∠B≅∠E and ∠C≅∠F

and

Hence, statement B. is true about the two triangles. "Angles A and D are congruent"

it is a. 4.2 because 7.6-3.4 gets the remaining length of 4.2. i might be wrong but i am pretty sure this is the answer.
