Here, we'd want x as the hypotenuse (as that is the longest part of a right triangle). So, 6 cm and 9 cm would be the legs.

 

Using the Pythagorean theorem, we can find the value of x:

 

62 + 92 = x2

36 + 81 = x2

117 = x2

x = √117, so I'd think that would fall under E) Other. :D

I agree (it is very important to learn and understand the Pythagorean theorem in order to solve and enjoy complex problems.)

 

Here to help
