Answer:
0
Step-by-step explanation:
A tangent line is a line that touches the circle's circumference at only one point.
Given two concentric circles one with radius [tex]r_1[/tex] and the second with radius [tex]r_2[/tex], and [tex]r_1>r_2[/tex]. SInce [tex]r_2[/tex] is inside the smaller circle, there is no way it would intersect with the tangent line t.
Therefore, there are no points of intersection between the tangent line t and [tex]r_2[/tex] .
