In order to find the hypotenuse of a right triangle, you must remember the theorem:
a² + b² = c².
40 to the second power is 1600, and 9 to the second power is 81.
Add these together for a total of 1681, but you're not done yet. We need to find what multiplied by itself equals 1681, since c is to the second power.
The sum must be larger (not equal to) the longest side. If it's exactly the same, there's no room to for the shorter two sides to angle up to form a triangle.
