# Math Help - Solving a triangle with only 2 sides?

1. ## Solving a triangle with only 2 sides?

I have an obtuse scalene triangle. The sides are "x" feet, "y" feet, and "z" feet...where x < y < z. If I know x and z, is it possible to solve for y without knowing any of the angles? If so, could someone supply the equation(s) necessary?

Nope.

No, all you can say is that $y > z - x$, or you wouldn't be able to draw the triangle; and that $y < \sqrt{z^2 - x^2}$, or the triangle wouldn't have an obtuse angle.
