Question

after bisecting an angle measuring 43.2°, matthew has two angles. what is the measure of each new angle?

Explanation:

Step1: Recall angle bisector definition

An angle bisector divides an angle into two equal parts. So we need to divide the original angle measure by 2.

Step2: Calculate the measure of each new angle

The original angle is \( 43.2^\circ \). To find the measure of each new angle, we perform the division: \( \frac{43.2^\circ}{2} = 21.6^\circ \).

Answer:

\( 21.6 \)
