Question

In the circle below, O is the center and mGl= 145°. What is the measure of the central angle ZGOR? H G 0 145° I​

Answer 1

The measure of the central angle is 290 degrees

How to determine the measure of the central angle?

The measure of arc GI is given as:

mGI = 145 degrees

The measure of the central angle is calculated as:

Central angle = 2 * mGI

Substitute the known values in the above equation

Central angle = 2 * 145

Evaluate the product

Central angle = 290

Hence, the measure of the central angle is 290 degrees
