Okay, so there is circle S. There are two tangents of this circle that intersect, so it almost looks like a cone? the angle of the intersected tangents is 20º. The arc that the "cone" intersects is 4x. I have to figure out what X is. THe answer is 110 but I don't know how to do it.
To get a numerical answer for the arc length, you need to specify the radius of the circle... not just the angle between the tangents.
I also do not understand your symbol
following the number 20.
