Question

The image shows a circle centered at point O angle AOB Measures at 42 degrees.

Answer 1

The measure of angle ACB for circle centered at point O is 21°

What is an equation?

An equation is an expression that shows the relationship between two or more numbers and variables.

∠AOB = 2 * ∠ACB (angle at center is twice the angle at circumference)

42 = 2 * ∠ACB

∠ACB = 21°

The measure of angle ACB for circle centered at point O is 21°
