By converse of isosceles triangle theorem, 5x+5=7x-1

5x+5=7x-1
-5x+5x+5=7x-5x-1
5=2x-1
5+1=2x-1+1
6=2x
6/2=2/2x
X=3

AC=6x+7 when x=3

6x+7=6 (3)+7=18+7=25

AC=25

6x+7+5x+5+7x-1=180 combine all like terms 6x+5x+7x=18x 7+5-1=11 rewrite 18x+11=180 subtract 11 from both sides 169 rewrite 18x=169 divide 18 from both sides witch is 9 x=9 plug 9 in for x 6(9)+7=54+7=61 AC=61
