Answer:
136
Explanation:
In a circle, the measure of an inscribed angle is half the measure of the arc it intercepts. Therefore, if the inscribed angle in a circle measures 68 degrees, the opposite arc will measure twice that, which is:
Opposite arc = 2 * Inscribed angle
Opposite arc = 2 * 68 degrees
Opposite arc = 136 degrees
So, the angle of the opposite arc would be 136 degrees.
