Answer:

$\angle AOC=66$

Explanation:

For two intersecting chords, the angle formed is half the sum of the measure of the arcs intercepted by the angle and its vertically opposite angle.

This means that:

$58\degree=(1)/(2)( 50+\angle AOC)$

Multiply through by 2 to get:

$116=50+\angle AOC$

Subtract 50 from both sides;

$\angle AOC=116-50=66$

$\angle AOC=66$
