Triangle ABC is congruent to triangle DEF. In triangle ABC, side AB measures 4, side BC measures x+8, and side CA measures 8. In triangle DEF, side DE measures 4, side EF measures 3x+3, and side FD measures 8. What equation would help you to solve for the side length of BC and EF? Explain your reasoning using complete sentences.

Best ResponseYou've already chosen the best response.2x + 8 = 3x + 3 subtract x from both sides 8 = 2x + 3 add 3 to both sides 11 = 2x divide both sides by 2 x = 5.5

Best ResponseYou've already chosen the best response.2oops i made an error.. 8 = 2x + 3 subtract 3 from both sides 5 = 2x x = 2.5

Best ResponseYou've already chosen the best response.2or 5/2 thats the value of x now you have to plug this into x + 8 to find the length of BC and EF.
