Since this is a right triangle, use the Pythagorean Theorem to find c. Pythagorean Theorem ⇒ a² + b² = c², where a and b are the legs and c is the hypotenuse.
Plug in 10 and 24 for the legs and c for the hypotenuse. 10² + 24² = c² 100 + 576 = 676 √676 = 26
To solve this we will use the Pythagorean Theorem, which is a²+b²=c²., where a and b are the legs and c is the hypotenuse. As we already know the lengths of the legs we will plug the length into the theorem below.
24²+10²=c² 576+100=676
Now we need to find the square root to get c by itself.
