Question

# Each of the two equal sides of an isosceles triangle is 1 cm less than the third. If its perimeter is 16 cm, find the sides of the triangle.

Solution

## R,E.F imageLet the third side, Bc be x cm Then, the other sides = (x - 1),(x - 1) cm each$$\therefore$$ Perimeter = 16$$\therefore (x-1)+(x-1)+x=16$$3x - 2 = 163x = 18x = 6 cmAB = AC = 5cm , BC = 6 cmMathematics
