Answer:
Step-by-step explanation:
Rate = 10%
Time = 2 years
Initial CO2 = 280000 metric ton
1st year
10% × 280000
= 28000 metric ton.
2nd year
10% × (280000 - 28000)
= 25200 metric ton.
Metric ton of CO2 produced at the end of the 2nd year = 252000 - 25200
= 226800 metric ton of CO2.
Answer:
Step-by-step explanation:
In any right triangle, the cosine of an angle is equal to its adjacent side divided by the hypotenuse, or longest side, of the triangle.
Therefore, we have:
