Me answer the first question! it would me out a

Since this is a right triangle, we can use the pythagorean theorem, , to solve for the hypotenuse as such:

Even though √250 is the right answer, we can simplify it thanks to the product rule of radicals (√ab = √a x √b) as such:

√250 = √25 x √10 = 5√10

The length of the hypotenuse is 5√10, or approximately 15.81, cm.
