Find the measure of central 鈭�1.

Short Answer

Expert verified

The measure of angle 鈭�1 is 150掳.

Step by step solution

01

Step 1. Given information:

The given figure is,

02

Step 2. Concept used:

In the circle the measure of arc is given.

Opposite angles are equal and the arc is equal to the angle that is asked.

03

Step 3. Applying the concept:

Here, we can see that in the figure.

Since both are vertically opposite angle so

Measure of arc =150掳

As we know,

鈭�1= measure of arc

=150掳

Therefore, the measure of the angle 鈭�1 is 150掳.
