Gutters for decahedron “turret”

Guys,
My house has a turret and, were it a castle in Disneyland, would be 10-sided. In reality only 5 sides are there and I need to put gutters on it. My question: Is there a way to join sections of gutter at the required 36 degree angle? I would prefer to use K-style as it would go with the rest of the house. Any help would be appreciated.

Sure, miter it. make one side of the miter about 3/4" longer than the other side, and snip ears that will engage with the mateing pc. Then poprivet them together and use plenty of gutter seal.
Use a chopsaw (12") to make a template of the miter, and use that to trace the profile on your stock. We solder copper, but Alum and rivits work well, if you don't over do what is visible.

pretty sure the miter angle cut pattern would be 18° to the gutter itself
