Question

This perimeter of a triangle is 4x-8,one of side is(2x-4),find the third side and another is 3x+8.

Answer 1

Answer:

The third side is (- 1 x - 12)

Step-by-step explanation:

First side of triangle (a) = 2 x - 4

Second side of triangle (b) = 3 x + 8

Perimeter of triangle = 4 x - 8

a + b + c = 4 x - 8

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

c + 5 x + 4 = 4 x - 8

c = 4 x - 8 - 5 x - 4

c = - 1 x - 12

Third side of triangle (c) = - 1 x - 12
