Solve.A carpenter wants to make a semicircular deck by cutting four equal pieces of wood as shown. Measure the angle of one of the pieces. Describe another way to determine the angle measure without using a protractor.
A. 90°; Since two of the pieces form a right angle, one of the pieces measures 1/2(180°), or 90°.
B. 40°; Since two of the pieces form a right angle, one of the pieces measures 1/2(80°), or 40°.
C. 45°; Since two of the pieces form a right angle, one of the pieces measures 1/2(90°), or 45°.
D. 60°; Since two of the pieces form a right angle, one of the pieces measures 1/2(120°), or 60°.
