Question 1187807: One side of triangle has an equation of 2x - 5 next side has 3x + 20 and the last side has 2x. I need to solve for x
My answers: x = 3
I'm having trouble because I know the sums of the interior angles are supposed to be 180 and when I replaced x with 3 for all sides it wasn't 180. Or maybe I'm wrong and the answer is 3

So those expressions are for its sides.


Maybe that is enough for you to continue and find the possible solutions for x.

The first two inequalities give invalid parts of a solution.
The last equation gives a meaningful inequality solution.

--------------------
Makes no sense.
The sum of the angles is 180, not the sum of the sides.
