Answer:

x° = 43°

Explanation:

You want the measure of the angle marked x° in the circle with arcs of 152° and 122° shown.

Inscribed angle

The arc subtended by the inscribed angle x° will be the measure of the arc that makes up the rest of the 360° circle:

360° -152° -122° = 86°

The measure of angle x° is half the measure of the subtended arc:

x° = 86°/2

x° = 43°
