 Question 752463: How to solve this question? Each interior angle of a Regular polygon is 170 Degrees. Calculate the number of sides in the polygon. Click here to see answer by stanbon(57399)

 Question 752341: a standard sign is a rectangle with measurement 36 in. by 12 in. The sheet metal they're to be made of measures 60 in. by 90 in. What is the maximum number of signs that can be made from the sheet metal. I tried dividing the area of the signs (432 in. ) into the area of the sheet metal (5,400), and I get 12 with some leftover material. The question is multiple choice, though, and 12 is not an option. Only 5, 8, 9, and 10. Click here to see answer by josmiceli(9697)
