Question

The perimeter of the triangle shown is 182 inches. Find the length of each side.

Answer 1

Answer:

5x=45, 7x+3=66, and 7x+8=71

Step-by-step explanation:

5x+7x+3+7x+8=182

Rearrange

5x+7x+7x+8+3=182

Add everything up

19x+11=182

Subtract 11 from both sides

19x=171

Divide both sides by 19

x=9

Plug x=9 into all spaces with x

5*9=45 , 7*9+3=66 , and 7*9+8=71

Voila!
