I think the answer is 8, I’m not sure
The answer is A because all the angles in a triangle add up to 180 degrees
We know that
Two circles in the same plane are internally tangent<span> if they intersect in exactly one point and the intersection of their interiors is not empty.
case (</span>A and B)--------> <span>are </span>externally tangent<span>
case (A and C)--------> </span><span>are </span>externally tangent<span>
case (B and C)</span>--------> are internally tangent
therefore
the answer is
the option B and C
