Length of the party of AB of a triangle is more than length of the party of BC on 12 cm. If to increase length of AB by 13 cm, and to increase length of BC by 6 times, then equal pieces will turn out. Find length of the party of AB x - Length of AB (x-12) - Length of BC x+13=6(x-12) 5x=13+72 of x=85/5 x=17 (cm) - length of the party of AB
