Angle XYZ is formed by segments XY and YZ on the coordinate grid below: A coordinate plane is shown. Angle XYZ has endpoints at 3 comma negative 1 and 6 negative 2 and 3 comma negative 3 and measures 36.87 degrees. Angle XYZ is rotated 270 degrees counterclockwise about the origin to form angle X′Y′Z′. Which statement shows the measure of angle X′Y′Z′? m∠X′Y′Z′ = m∠XYZ m∠X′Y′Z′ = 180 degrees m∠X′Y′Z′ = 270 degrees m∠X′Y′Z′ = 2 × m∠XYZ
