Question

please help:


triangle ABC is congruent to triangle DEF. in triangle ABC side AB measures 9, side BC measures 3x+1 and side CA measures 7. in triangle DEF side DE measures 9, side EF measures 2x+2, and side FD measures 7. what equation would help you to solve for the side length of BC and EF? explain your reasoning

Answer 2

@ganeshie8 are you there?

Answer 3

those two triangles were meant to be drawn congruent :)

Answer 4

but how would I answer this question using sentences? @perl

Answer 5

Since the triangles ABC and DEF are congruent, corresponding sides are congruent.Therefore sides BC and EF are congruent.

BC = EF

by substitution

3x+1 = 2x+2
