Answer:
B: 22.5 degrees
Step-by-step explanation:
The interior angles of a pentagon add up to 540 degrees
(if you dont believe me you can turn a pentagon into three triangles, 3x180 = 540)
So you have four same angles say measure "x" degrees, and one final one that measures "5x" degrees, so 9x = 540, and x = 60
Unless I read the problem wrong, 60 degrees is the answer which is not an option :P
Edit: Yea I read it wrong, the final angle is 5 times the other four angles COMBINED, so that angle measures "20x" degrees.
The total would be 24x = 540, and so x = 22.5
Answer:

Step-by-step explanation:
Pollution is not a new phenomenon. In fact, pollution has been a problem since the appearance of our earliest ancestors (Markham, 1994).

Answer:
3,051,490 cookies/day
Step-by-step explanation:
Do 610,298 x 5
270 minutes = 4,5 hours = 4 hours and 30 minutes
60 minutes = 1 hour
63 miles per 270 minutes
x miles per 1 hour = 60 minutes
![\dfrac{63[miles]}{x[miles]} = \dfrac{270[minutes]}{60[minutes]}](https://tex.z-dn.net/?f=%5Cdfrac%7B63%5Bmiles%5D%7D%7Bx%5Bmiles%5D%7D%20%3D%20%5Cdfrac%7B270%5Bminutes%5D%7D%7B60%5Bminutes%5D%7D)
![x=14[miles]](https://tex.z-dn.net/?f=x%3D14%5Bmiles%5D)
His average speed is 14 miles per hour.
