Answer:
No
Step-by-step explanation:
If segment AB is tangent to the circle, then angle CBA will be a right angle, making triangle ABC a right triangle. If triangle ABC is a right triangle, it's sides will fit the Pythagorean theorem...
(leg)^2 + (leg)^2 = (hypotenuse)^2
Does 8^2 + 16^2 = 19^2 ?
64 + 256 does not equal 361!
Triangle ABC is NOT a right triangle, so segment AB is not tangent to the circle.
