Question 992859
.
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.
