72 degrees because it isn't an obtuse angle so it can't be 108  or 144 and it is closer to 90 degrees. so 72 is the best answer

The corners should add up to 360°. Due to symmetry, the Mapel-Garden angle equals Maple-Elm, both are 108. That leaves 360-108-108 = 144° for the other 2 angles. Divide that equally and both should be 144/2 = 72°, answer B.
