Use the Pythaogorean Theorem to determine the exact length of AB.
Express the answer as A) an exact value in simplest mixed radical form
B) A decimal to the nearest hundredth
The picture is right here, I uploaded it of the diagram.

AD^2 + 8^2 = 12^2
AD^2 = 80
BD^2 + AD^2 = AB^2
36 + 80 = AB^2
AB = √116 or 2√29
