Question

an angle is bisected, forming two new angles. each new angle has a measure of 13°. what was the measure of the original angle?

Explanation:

Step1: Recall bisection concept

The original angle is twice the new - formed angle.

Step2: Calculate original angle

Let the original angle be $\theta$. Since each new angle is $13^{\circ}$, then $\theta = 2\times13^{\circ}$.
$\theta=26^{\circ}$

Answer:

$26$
