Sounds like a geometric progression. Initial value is $30,000; p is the annual increase, a percent, but expressed as a decimal fraction between 0 and 1; n is the number of years.
Total salary = $30,000 (1+p)^n, or, in shorthand and following the wording of this problem,
Total salary = $30,000 x^n, where x = 1 + p
The answer would be 124 degrees I believe because if it is vertical you would just have to subtract 56 from 180.

Answer: The length of BC ≈ 12.4 cm
Step-by-step explanation:
The first thing we need to do is to find the length of BD which we can solve for with the tangent of 20° which is the opposite side over the adjacent side.
We get tan20° = BD/8.
Solve for BD and you get BD = 8tan20°.
Now we will need to solve for the length of CD which we can get from the tangent of 40°.
We get tan40° = 8/CD
Solve for CD and you get CD = 8/tan40°.
Now that we have the lengths of BD and DC, we can simply add them together to get the length of BC.
(8tan20°) + (8/tan40°) ≈ 12.4 cm
