Answer:
It is not tangent
Explanation:
If it were tangent, that angle A would have to equal 90 degrees since that just the definition of a line tangent to a circle, its perpendicular to the radius.
If it were tangent, then we could use the pythagorean theorem to check if this is a right triangle and actually has angle A with 90 degrees. a^2+b^2=c^2
4^2+12^2 does not equal 13^2.
If segment AC was 5, then it would be tangent but since its 4, the pythagorean theorem doesnt match up and therefore, it doesnt make a 90degree angle
If you dont understand my stupid explanation thats hard to explain then search this up on google
