Question

an angle is bisected, forming two new angles. each new angle has a measure of 55°. what was the measure of the original angle?

Explanation:

Step1: Recall angle bisector definition

An angle bisector divides an angle into two equal parts. So the original angle is the sum of the two new angles.

Step2: Calculate original angle

Each new angle is \( 55^\circ \), so original angle \( = 55^\circ + 55^\circ = 110^\circ \)

Answer:

\( 110 \)
