Question

The three sides of scale triangle are,2X+3, 2(X+1) and 5X-1. if the perimeter of triangle is 22cm find the measure of each side​

Answer 1

Answer:

Perimeter=a+b+c

22= 2x+3 + 2x+2 + 5x -1

22= 9x + 5 -1

22= 9x + 4

9x = 22 - 4

9x = 18

x = 18/9

x = 2

Put value of x in above equations in statemnt.

Therefore: 2x+3 = 7

2x+2= 6

5x-1= 9
