For this problem, we are going to use the <em>law of sines</em>, which states:
In this case, we have an angle and two sides, and we are trying to look for the third side. First, we have to find the angle which corresponds with the second side, 
. Then, we can find the third side. Using the law of sines, we can find:
We can use this to solve for :
Now, we can find 
:
Using this, we can find 
:
c is approximately 17.5.
The sum of 2 opposites =0
X+6 would now equal 0
So your answer is 0
Answer:
Since the difference between the value for each year is constant, this is an arithmetic sequence.
Step-by-step explanation:
Year 2 - Year 1 = 21,750 - 20,000 = 1,750
Year 3 - Year 2 = 23,500 - 21,750 = 1,750
Year 4 - Year 3 = Year 5 - Year 4 = 1,750
