Answer:
f = 66°
Step-by-step explanation:
The measure of the chord- chord angle is half the sum of the measures of the arcs intercepted by the angle and its vertical angle , that is
88° = [tex]\frac{1}{2}[/tex] ( sum of opposite arcs to 88° ) ← multiply both sides by 2
176° = sum of opposite arcs.
The sum of the arcs around a circle is 360°, then
f = 360° - (118 + 176 )° = 360° - 294° = 66°
