Question

a peremeter of a triangle is 4x–8 , one of the side is 2x–4 and another is 3x+8. find the third side.​

Answer 1

Step-by-step explanation:

Let the third side be x

According to the question,

x+2x-4+3x+8=4x-8

6x+4=4x-8

6x-4x=-8-4

2x=-12

x=-12/2

x=-6

Answer 2

Let third side be a
P = 4x - 8
A/q. 2x-4 + 3x+8 + a = 4x - 8
5x +4 + a = 4x - 8
a = -x -12
a = -(x+12)
