Hi, Welcome.
Question not real clear. I'm guessing it is a round light house. Is that around the circumference so it would be an 8 sided piece or the roof pitch? If being the circumference it would really be the opposite of 68 which is 22. That comes from a starting point of 90 - 68 = 22. If 8 sided the cuts would be 22.5. Added all together it would equal 360 (full circle).

If for the roof pitch (taper)I would make a simple tapering jig to use with the table saw. It would still probably be a compound cut so you would need to tilt the blade to the degrees needed to make a circle when glued together. The math to make a complete circle is 360 (number of sides) gives joint degrees. Divide that by 2 gives cut degrees for each side of joint.

Example for 8 sides: 360 8(sides) = 45 2 = 22.5
Your cuts will be 22.5 on each end of your pieces. Put together you will have a complete circle. The length of each piece would depend on the total circumference that you need.

Have a nice & safe day!
