Question

An arc on a circle measures 125°. What is the measure of the central angle?

Answer 1

`125^@`

Explanation:

A theorem in geometry is:

The degree measure of a minor arc is the same as it's central angle.

In this example, a `45^@` arc has a `45^@` central arc.

In your circle, the arc is `125^@`, so the central angle is also `125^@`
