Question

in the figure on the right, the lenght of the segment A must be x + 3, the length of segment B must be x +2, and the length of segment C must be x + 1. the perimeter of the triangle is 30cm. equate the sum of the lengths of the segments to 30 and solve for x

Answer 1

x=8

Explanation:

A= x+3

B= x+2

C= x+1

A+B+C=30

`x+3+x+2+x+1=30\\3x+6=30\\3x=30-6\\3x=24\\x=(24)/(3)\\x=8`

ANS: X=8
