Answer 1

Step-by-step explanation:

let the sides be 13x,14x, and 15x.

we know that the perimeter of the triangle is the sum of all sides.

according to the question,

13x+14x+15x = 84

42x = 84

x = 84/42

x = 2

find the sides putting tow Inthe place of X.

I can do this but I want to give this to you and you do not need more it.
