Question

the perimeter of the triangle is 4 x-8 one side of the is 2x - 4 then other is 3 X + 8. find the third side​

Answer 1

Answer:

Heya!

Step-by-step explanation:

The third side is (- 1 x - 12)

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

Answer 2

Answer:

perimeter of triangle is a + b + c

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

- x - 12 = c
