Question

angle ABC is inscribed in a circle as shown.

What is the measure, in degrees, of angle ABC.

Answer 1

This is an accute angle so it is less than 90 so i woyld say it looks to be around 70 but try to use a protracter

Answer 2

The measure of an angle inscribed in a circle is half the measure of the intercepted arc. Since angle ABC intercepts arc AC, the measure of arc AC is double 70 degrees. Arc ABC is the rest of the 360 degree circle . Subtract 140 degrees from 360 degrees.
