Question

Can someone teach me how this goes? geometry , inscribed angles but circles

Answer 1

60

Explanation:

So basically all you need to know for this one is that when there is an inscribed angle, the angle measure is 1/2 of the measure of the arc for that angle.

That might sound confusing, but an example from the picture is that angle ABC will be half of arc AC. This means that angle ABC is 1/2 of 120 = 60 degrees.

The answer is 60 degrees.
