Answer:
The line AB is not tangent to circle O
Explanation:
we know that
If AB is tangent to circle O at point B
then
AB is perpendicular to OB (radius) and ABO is a right triangle
Verify
Applying the Pythagorean Theorem

substitute the given values


-----> is not true
so
The triangle not satisfy the Pythagorean Theorem
therefore
The line AB is not tangent to circle O
