If the angle between two tangents drawn from an external point to a circle of radius 'r' is 60 degrees, find the length of each tangent.
Ar
Br * sqrt(3)
Cr / sqrt(3)
D2r
✓ Correct Answer: B — r * sqrt(3)
In the triangle formed by radius, tangent, and line to center, tan(30) = r/L. L = r / tan(30) = r * sqrt(3).
