For Exercises 1 to 8, use the figure provided. Exercises 1-8If m D E ⌢ = 47.6 ∘ ,  find m ∠ O .

To determine

To calculate:

The mO by using the provided figure.

Explanation

Given:

The provided figure is

Postulate:

Central angle postulate:

In a circle, the degree of a central angle is equal to the degree measure of its intercepted arc.

Calculation:

We need to find mO.

Since, mDE=47.6o

There is a theorem says that, in a circle, the degree of a central angle is equal to the degree measure of its intercepted arc.
