Answer:
41
Step-by-step explanation:
This is a pythagorean theorem question, which is represented by the formula [tex]a^{2} + b^{2} = c^{2}[/tex]
c always represents the hypotenuse, which is the longest side of the triangle
your two given numbers are represented by a and b
plug in the two numbers into the formula and solve. the formula should look like this: [tex]9^{2} + 40^{2} =c^{2}[/tex]
it should then be: 81+1600=[tex]c^{2}[/tex]
Add the two numbers and take the square root
