Question

I could use some help with this one please.


Triangle ABC is congruent to triangle DEF. In triangle ABC, side AB measures 13, side BC measures x+13, and side CA measures 16. In triangle DEF, side DE measures 13, side EF measures 3x−20, and side FD measures 16. What equation would help you to solve for the side length of BC and EF? Explain your reasoning using complete sentences.

Answer 1

they're congruent so ABC = DEF
13 + x + 13 + 16 = 13 + 3x - 20 + 16
all the side lengths of ABC are = to DEF
