You can put this solution on YOUR website!
Sorry, but there is something wrong with your problem statement. Either you have a rectangle rather than a square as you said, or the legs of the triangle are both the same.
Since the legs of the triangle are different, I'll presume a rectangle. Since it is a rectangle, the included angle of the two side lengths given must be a right angle, but definition of a rectangle. So the triangle must be a right triangle.
Just use the Pythagorean Theorem:
So, for this problem c = x, and a and b are 3 and 5, so:
You can use a calculator as well as I can, although if your instructor expects the exact representation of the answer, you need to leave it in radical form.
