a
Step-by-step explanation:
agree that AOB + BOC = AOC, right?
AOC = 25 = (4x - 15) + (2x + 10) solve for x first
25 = 6x - 5, now add 5 to both sides
30 = 6x divide both sides by 6, so x = 5
now substitute: BOC = 2x+10 = 10 + 10 = 20
AOB = 4x - 15 = 20 - 15 = 5

7918
Step-by-step explanation:
If you round Earth's diameter, I believe that it is 7,918 miles.
Answer:
s for length of either equal side
b for the unequal side
b=-2+2*(s+s) and 2s+b=40
b=2*2s-2
b=4s-2
2s+4s-2=40
6s-2=40
6s=42
s=7
b=4*7-2
b=28-2
b=26
