Step-by-step explanation:

Look at the attached figure to see the scenario. Now notice that the situation creates a Right Triangle and what we need to find is the hypotenuse, which is the longest side of the triangle, which is across the right angle.

To solve this you need to remember the Pythagorean Theorem.

c = hypotenuse

a and b are the other legs of the triangle. So let's get what we know and plug it into the formula:

answer:

c. the third graph
