If you have any questions about the way I solved it, don't hesitate to ask me in the comments below
P.s: I used the Law of Sines, but there are many other ways to solve it
The area of a polygon equals
area = circumradius² * number of sides * sin (360 / # of sides) / 2
area = 77² * 20 * sin (360 / 20) / 2
area = 77² * 20 * sin (18) / 2
area = 118,580 * 0.30902 / 2
area =

In fractions, the shaded area would equal 1/2
or 0.5
or 50%
