Best ResponseYou've already chosen the best response.1In 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.

Best ResponseYou've already chosen the best response.1It'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.
