Question 1080010: Chord AB has the same length as the radius of the circle in which it is drawn. Endpoints of a chord AB are points of tangency of two lines to this circle. These two tangents intersect each other at point C. What is the measure of angle ACB? Answer by ikleyn(52855) (Show Source):
HINT #1. The chord and the radii make an equilateral triangle with interior angles of 60°.
Hint #2. The tangent lines at the tangent points are perpendicular to the radii.
Based on these hints, can you complete the solution on your own ?
