Answer:
45
Step-by-step explanation:
b and c are part of an 180 degrees angle.

90/2=45
And b and c are vertical angles
Answer:
The population of the United States is 387.87 times larger than the population of Columbus, Ohio.
Step-by-step explanation:
8.25 times 10^5 = 825,000
3.2 times 10^8 = 320,000,000
320,000,000 divided by 825,000 = 387.87
