The polygon shown is a regular decagon (10 sides). The formula to find the measure of each interior angle of a regular polygon is:
Interior Angle = [(n - 2) × 180°] / n
where n is the number of sides.
For a decagon (n = 10):
Interior Angle = [(10 - 2) × 180°] / 10 = (8 × 180°) / 10 = 144°
Therefore, the measure of each interior angle is 144.0°.
