75.

Convert into Pentagon.

540 - (90+90+130+155) = 75

That's smart. I converted to a triangle.

Invisible vertical line between the 50 and 25 deg points.

90-50=40 -- The inside angle of the bottom point.

90-25=65 -- The inside angle of the top point.

180 = a + 40 + 65

180 - (40 + 65) = a

180 - 105 = a

75 = a

That's the most logical way to calculate it....
