Question

// * PLEASE ANSWER * // AB is tangent to circle C. Find AC to two decimal places.

Answer 1

19.92

Explanation:

To find the length of AC we need to use the Pythagorean theorem: a^2 + b^2 = c^2

a = 6 b = 19

a^2 = 36

b^2 = 361

36 + 361 = 397

c^2 = 397

to find c we take the square root of 397

`√(397) = 19.9248588452`

take the first 2 decimals for the answer
