Question

Hi ....

The perimeter of a triangle is 18p+12q+13r and two of its sides are 5p+3q-4r and 6p+5q+7r. Find the third side.

Answer 1

Answer:

The third side is 7p+4q+10r

Step-by-step explanation:

Given,perimeter =18p+12q+13r

two sides are

5p+3q-4r and 6p+5q+7r

let third side be x

then,

5p+3q-4r+6p+5q+7r+x=18p+12q+13r

11p+8q+3r+x=18p+12q+13r

x=18p+12q+13r-11p-8q-3r

x=7p+4q+10r
