The answer is the first row.
Explanation:
8 * 10^7 = 80,000,000 -- 2 * 10^4 = 20,000
80,000,000 divided by 20,000 = 4,000, so it is 4,000 times larger
Therefore, the first answer is correct.
Hope I helped and good luck!

Answer:
a = 70°
b = 80°
Step-by-step explanation:
Angles on a straight line add up to 180°
⇒ a + 110 = 180
⇒ a = 180 - 110
⇒ a = 70°
The sum of the interior angles of a quadrilateral is 360°
⇒ a + b + 130 + 80 = 360
⇒ 70 + b + 130 + 80 = 360
⇒ b + 280 = 360
⇒ b = 360 - 280
⇒ b = 80°
