Answer:
(c) 61°
Explanation:
You want the measure of the external angle formed by a tangent and secant that intercept arcs of 73° and 195° of a circle.
External angle
The measure of the angle at F is half the difference of intercepted arcs HE and EG.
(195° -73°)/2 = 122°/2 = 61°
The measure of angle F is 61°.
