Answer:

Roy is incorrect.

Step-by-step explanation:

The price of the item has already had 15% taken of. 15% off of $100 is $85.

Now take 10 percent of off that, and you get $76.50. If you were to take twenty-five percent off of the original $100 like Roy said, you would have got $75. Although It is only a small difference, Roy is still wrong.

kramer

Answer:

40° and 9°

Step-by-step explanation:

The sum of the exterior angles of a polygon = 360°

If the polygon is regular then the measure of each exterior angle is

\frac{360}{n} ← where n is the number of sides

(a) for a regular 9 sided polygon

exterior angle = \frac{360}{9} = 40°

(b) for a regular 40 sided polygon

exterior angle = \frac{360}{40} = 9°
