Question

HELP PLEASE!!!!!!!!!!!!!!!!

Answer 1

Explanation:

NQ is a tangent line. That means that where it meets the circle results in a right angle. Therefore, we have a right triangle where XQ is the hypotenuse. Using Pythagorean's Theorem,

`20^2=8^2+x^2` where 8 is the radius because the diameter is 16.

400 - 64 = x² and

336 = x² so

x = 18.3 which is the length of NQ
