Question

A. The perimeter of a triangle is 16x' +14x? - 9x + 15. If two of its sides are 7x + 3x? - 2x + 3
4x + x - 5x + 7, find the third side.
​

Answer 1

Let the third side x

Given:-

Sides of triangle=7x+3x-2x+3 , 4x+x-5x+7

Perimeter=17x+14x-9x+15

Perimeter=Sum of all three sides

x+(7x+3x+2x+3)+(4x+x-5x+7)=16x+14x-9x+15

=>x+7x+3x+2x+4x+x-5x+3+7=16x+14x-9x+15

=>13x+10=21x+15

=>13x-21x=15-10

=>-8x=5

=>x=5/8

=>x=0.62
