Question

two equal sides of isosceles Triangles are 3 X - 1 and 2 X + 2 units the third side is 2x units find X and perimeter of triangle

Answer 1

if 3x-1 and 2x+2 are equal sides of an isosceles triangle then they must me equal

therefore,

3x-1 = 2x+2

x=3

sides are--

3x - 1= 3(3) - 1 = 8

and unequal side = 2x = 6

perimeter = 8+8+6 = 22 units
