Answer: Option 'C' is correct.
Step-by-step explanation:
Since we have given that
∠AOT=60°
Consider Δ ATO,
As we know that the radius always forms right angle at the tangent, as the radius is the shortest distance to it .
So, ∠OAT=90°
As we know that "Sum of interior angles of the triangles is supplementary":
[tex]\angle A+\angle ATO+\angle AOT=180\textdegree\\\\90\textdegree+60\textdegree+\angle ATO=180\textdegree\\\\150\textdegree+\angle ATO=180\textdegree\\\\\angle ATO=180\textdegree-150\textdegree\\\\\angle ATO=30\textdegree[/tex]
so, the angle between the tangent is given by
[tex]2\times 30\textdegree=60\textdegree[/tex]
Hence, Option 'C' is correct.
