Question

giving the picture , what is the length of ac

Answer 1

You just have to use the Pythagorean Theorm. The general formula is : a^2 + b^2 = c^2

Then sub the values into the the equation :

(8)^2 +(4)^2 = c^2
c^2 = 64 + 16
c^2 = 80
c = square root of 80
c = 8.94 (approx.)

So the answer is AC = 8.94.
