Question

after bisecting an angle, tori has two new angles, each with a measure of 13°. what was the measure of the original angle?

Explanation:

Step1: Recall angle - bisector property

An angle - bisector divides an angle into two equal angles.

Step2: Calculate original angle

If the two new angles formed by angle - bisecting have a measure of $13^{\circ}$ each, then the measure of the original angle $\theta$ is given by $\theta=2\times13^{\circ}$.
$\theta = 26^{\circ}$

Answer:

$26^{\circ}$
