This polygon has six sides. The formula for the sum of the angles in a shape with x sides is: 180(x-2). Since this shape has 6 sides, the sum of the angles inside it is 180(6-2)=720 degrees. Now, you know that the sum of the angles must be 720 degrees, so sum up all the angles: 135+62+151+140+n+(n+6)=720 and solve for n.
