The given question describes a right triangle with with one of the angles as 20 degrees and the side adjacent to the angle 20 degrees is of length 5,000 feet. We are looking for the length of the side opposite the angle 20 degrees.

Let the required length be x, then

$\tan{20^o}=\cfrac{opp}{hyp}=\cfrac{x}{5,000}\\ \\ \Rightarrow x=5,000\tan{20^o}=1,819.85$

Therefore, the height of the airplane above the tower is 1,819.85 feet.

Lady bird [3.3K]

Answer:

Step-by-step explanation:

Annual gross salary = $28000

Income tax = 20% on anything above $15000

So she's taxable for $5000

Rent loan = $140 per month = $140 * 12= $1680 per annum

Tax deductible per annum = 20% of $5000

20 / 100 * $5000 = $1000

Total amount she takes home per annum =

Gross salary per annum - tax - loan =

($28000 - $1000 - $1680) = $25,320

Ayesha takes home $25,320 home annually.
