The perimeter of an isosceles triangle is 16cm the lengths of the sides are (x+3)(this is the length of the opposite side as well) and (x+4). Determine the value of x .

  1. Write out all the information you have into one single equation, you know that the perimeter is the sum of the lengths of the sides of the triangle so write out the information as follows. x+3 + x+3 + x+4=162) Collect like terms giving the equation 3x + 10=16) Rearrange to make x the subject of the equation to give x=2
