11. the pentagon's area if CM = 10 cm and WX = 11.8 cm
12. CM if the pentagon's area is 125 ft? and VW = 8.5 ft
13. Sam wanted to find m_ VWX, so he divided 360° by 5 and got 72°. But when he looked at the angle, he
realized it must be greater than 90°.
a. Explain Sam's error.
b. Find m2 VWX.
c. Make a conjecture relating the measures of an interior angle in a regular polygon and a central angle.
