What is the value of​ y? Lines that appear tangent are tangent. A circle contains two line segments. The first line rises from left to right, ending outside of the circle, intersecting the second line that is falling from left to right inside the circle. A third line, z, intersects the perimeter of the circle near the top and falls slightly from left to right, ending at the end of the first line, outside of the circle. Inside the circle, the top left line segment has length 10 and the bottom right line segment has length x. The bottom left line segment has length 9 and the top right line segment has length 6. The angle formed by the top and bottom left line segments in the circle measures y degrees and the arc formed measures 91 degrees. The arc formed by the top and bottom right line segments in the circle measures 33 degrees.
