Question

 Ex is tangent to circle O at point L, and IF is a secant line. If m_FLX = 104°, find
mLKF.

Answer 1

arc LKF = 208°

Explanation:

the angle FLX between the tangent and the secant is half the measure of the intercepted arc LKF , then intercepted arc is twice angle FLX , so

arc LKF = 2 × 104° = 208°
