Question

ΔABC is right-angled at C.If AC=5cm and BC=12cm find the length of AB.​

Answer 1

13

Explanation:

This is an application of the pythagorean theorem. Because C is centered at the right angle, AB must be the hypotenuse (I would draw this for you but I don't know how). Thus, we would get sqrt(5^2+12^2)=sqrt(169)=13.
