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.
Aremote-controlled boat can travel at 4 feet per second in calm water. the boat traveled 48 feet with the current, and then it traveled 16 feet against the current in the same amount of time. how fast is the current?
