Question

two equal sides of an isocles triangle are 3x-1 and 2x+2 the third side is 2x unit find x and the perimeter of the triagle

Answer 1

Answer

The perimeter of isosceles traingle is 22

Step by step explanation:

Two equal sides of an isocles triangle are 3x-1 and 2x+2

So the length = 3x - 1 = 2x + 2

= 3x - 2x = 2 + 1

= x = 3

So the x = 3

Perimeter of isosceles traingle =

Perimeter = sum of all side

let us consider the value of x be 3

perimeter = 3x - 1 + 2x + 2 + 2x

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

Perimeter = 9 - 1 + 6 + 2 + 6

Perimeter = 22

So the perimeter of isosceles traingle is 22
