Question

12. Find the remaining side of a triangle having perimeter 19x + y whose two sides are 4x + 3y and 10x – y.
​

Answer 1

Answer:

We take N as remaining side then we take perimeter of triangle a+b+c then our answer will come

Hope this answer helped a lot

Answer 2

Answer:

(5x - y)

Step-by-step explanation:

Given two sides of a triangle are 4x+3y , 10x -y

let the third side be a.

given perimeter 19x+y

sum of three sides of a triangle is perimeter

so. ( 4x +3y) +(10x -y) + a = 19x +y

14x +2y + a = 19x+y

then a = 19x+y -14x -2y

a = 5x -y

so the remaining side is 5x - y
