# For Exercises 1 to 8, use the figure provided. Exercises 1-8If m D E ⌢ = 46 ∘ ,  find m ∠ O .

To determine

To calculate:

The mO, by using the provided figure.

Explanation

Given:

The provided figure is,

Postulate used:

Central angle postulate:

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

Calculation:

To find: mO.

From the figure we see that O is the central angle.

Therefore, use central angle postulate.

From the figure, the intercepted arc is DE
