Question

two equal sides of an isosceles triangle are 3x - 1 and 2 X + 2 units .The third side is 2 x units .Find X and the perimeter of the triangle​

Answer 1

Answer:

two equal sides mean

3x-1=2x+2

3x-2x=2+1

x=3

perimeter of the triangle=sum of the three sides

=(3x-1)+(2x+2)+(2x)

=(3*3-1)+(2*3+2)+(2*3)

=(9-1)+(6+2)+(6)

=8+8+6

=22
