Question 653300
A triangle has 3 sides
the lenght of one side is 5cm
the other two sides are of the same lenght,: lets each be x, x respectively
the perimeter is 71cm
the perimeter is the addition of all the sides together; x + x + 5 = 71
                            2x = 71-5
                            2x = 66
                              x = 33cm
