right triangle with given hypotenuse help!

A right triangle with a hypotenuse 10 cm long is to have an area of 15 sq. cm. what should be the lengths of the legs? (Speechless)

If x & y represent the lengths of the legs then you know that:
[Math]\frac{{xy}}{2} = 15\;\& \;x^2 + y^2 = 100[/tex].
Solve for x & y.
