Question

if the base of an isosceles triangle be (x + 3) cm, equal sides are ( x + 2) cm and the perimeter of the triangle is 13 cm, then find the non equal side of the triangle

Answer 1

(x+2)+(x +2) +(x+3)=13 (since ut is an isosceles ..theefore its 2 sides are equal)

3x+7=13
3x=13-7
3x=6
x=2

non equal side of triangle is (x+3) that is of base put the value of x in this..so we get..2+3 = 5.cm
