Given two congruent chords determine the measure of x for an arc

The video tutorial covers the concept of congruent chords and their corresponding arcs in geometry. It explains that when two chords are congruent, their arcs are also congruent. The tutorial then demonstrates how to calculate the length of these arcs by setting up an equation where the sum of the arcs equals 360 degrees. The process involves solving for X, which represents the arc length, and concludes with a solution of X equaling 161 degrees. The session ends with an invitation for questions.

How do you derive the value of X from the equation 360 degrees equals X + X + 38?

What is the final value of X after solving the equation?
