two exterior angles are also 90°
The remaining exterior angles (all the same), are 180-120 = 60°
The exterior angles add to 360°, so there are 3 more of them, each 60°.
The figure is a pentagon similar to a home plate in baseball.
Consider that the interior angles of a hexagon are all 120°. Drawing a diagonal between two adjacent sides will form this figure.
