Question:
Find the length of AC.
Solution:
Applying the Pythagorean Theorem, we get:
[tex]AC\text{ = }\sqrt[]{CB^2_{}-AB^2}\text{ = }\sqrt[]{13^2_{}-5^2}[/tex]
this is equivalent to:
[tex]AC\text{ = }\sqrt[]{13^2_{}-5^2}\text{ = }\sqrt[]{144}=12[/tex]
then, we can conclude that the length of AC side is:
[tex]AC\text{ }=12[/tex]
