Circle $\Gamma$ is the incircle of $\triangle ABC$ and is also the circumcircle of $\triangle XYZ$. The point $X$ is on $\overline{BC}$, point $Y$ is on $\overline{AB}$, and the point $Z$ is on $\overline{AC}$. If $\angle A=40^\circ$, $\angle B=60^\circ$, and $\angle C=80^\circ$, what is the measure of $\angle AYX$?

Let O be the centre of the circle.
OX=OY equal radio
So
OXY is an isosceles triangle
120+2
so
< AYX =
I am sorry, this was a full answer but 3/4 of it has been deleted.
There is obviously a software problem.
I shall report it as a problem :/
See the following image :
Construct angle bisectors of each vertex angle of triangle ABC
Angle AYC = 180 - angle ACY - angle YAC = 180 - 40 - 40 = 100°
Angle AOC = 180 - angle OAC - angle OCA = 180 - 20 - 40 = 120°
And angle YOX is a vertical angle to angle AOC ....so it measures 120°
And since they are equal radii, OY = OX
So angle OYX = angle OXY
So triangle OYX is isosceles
And.....angle OYX = [ 180 - 120 ] / 2 = 60 / 2 = 30°
And AYX = angle AYC + angle OYX = 100 + 30 = 130°
