In a 306090 degree right triangle, the shorter leg is half of the hypotenuse, so the hypotenuse is 25. Now, let "x" be the length of the longer leg: x^2 + 12.5^2 = 25^2 x^2 = 25^2  12.5^2 So, just solve for "x" by squaring both terms on the right, adding them, and then taking the square root of that sum.

That's rounding a bit too much.

It's an irrational number, so if you want it in decimal form, it has to be approximated. The decimal points will go on forever otherwise.
