Given:
An Angle is bisected, forming two new angles.
The original angle had a measure of 81.9°
We need to determine the measure of each new angle.
Measure of each new angle:
The measure of each new angle can be determined by dividing the original measure by 2.
Thus, we have;

Dividing, we get;

Hence, the measure of new angle is 40.95°
Thus, the measure of each angle formed is 40.95°
