Wouldnt it be 15??? I would guess so. Katie keeps deleting this but Im not sure why. Sorry katie but I really need help

25 in; C

Step-by-step explanation:

Hey!

There probably is a reason she is deleting. You could contact her or ask some help elsewhere.

Anyway! I'm trying to get this in fast. (Remember the Pythagorean Theorem?) That will be very useful here since it is a right triangle.

L² + L² = H² (or H² - L² = L²):

In that case, we'll use the second one because our Hypotenuse is given.

We can substitute each value of the numbers:

65² - 60² = L²

Evaluating:

4225 - 3600 = 625

√625 = 25 inches

Thusly, the third side would be

Also note we could have simplified into a Pythagorean Triple. This method is a simpler more basic method for learning the concept.

Hope this helps!
