You can put this solution on YOUR website! Two sides of a triangle are 3ft and 6ft longer then the third side. If the perimeter of the triangle is 36ft find the lenght of each side
let x= length of3rd side
x+3=2nd side
x+6 =1st side
2(x+3+x+6)=36
4x+18=36
4x=18
x=4.5
x+3=7.5
3rd side=4.5 ft
1st side=7.5 ft
2nd side= 10.5 ft

Two sides of a triangle are 3ft and 6ft longer then the third side.
If the perimeter of the triangle is 36ft find the lenght of each side
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
This problem is solved incorrectly in the post by @lwsshak3.
For correct solution, see what follows in my post.
let x be the length of3rd side
x+3 = 2nd side
x+6 = 1st side
x + (3+x) + (x+6) = 36
3x + 9 = 36
3x = 27
x = 9
3rd side is 9 ft long.
1st side is 9+6 = 15 ft long
2nd side is 9+3 = 12 ft long.
For these side lengths, the triangle inequalities are valid, so such triangle does exist.
Solved correctly for your right teaching/learning.
