Triangle ABC is congruent to Triangle DEF, segment BC = 4x - 7 and segment EF = 2x + 3, find the length of BC and EF. Make sure you show ALL of your work.
bc and ef are congruent so that means 4x-7 =2x+3 subtract 2x from both sides -2x -2x _________ 2x-7 = 3 add seven to both sides +7 +7 ________ 2x = 10 divide both sides by 2 __ ___ 2 2
