A triangle has a perimeter of 58 cm the longest side is twice as long as the shortest side the third side is 10cm longer than the shortest side what are the lengthes of the three sides?
shortest side= x   longest side= 2x  third side= 10cm+x 58cm=x+2x+10cm+x 58cm=4x+10cm 48cm=4x 12cm=x shortest side= 12cm  longest side= 24cm third side=22cm
