10^{3} $1 bills is the same as 10 \times 10 \times 10 = 1000 $1 bills.

You're told that 1000 $1 bills is 4.3 inches tall. That means to get the height of one $1 bill, you have to divide 4.3 inches (the height of 1000 $1 bills) by 1000 (how many bills there are):
 \frac{4.3}{1000} = 0.0043 in

The thickness of one $1 is C) 0.0043 in.

erik [133]

The angle of depression from the aeroplane to the ground​ will be 30 degrees.

<h3>What is trigonometry?</h3>

Trigonometry is the branch of mathematics which set up a relationship between the sides and angle of the right-angle triangles.

Given that:-

  • An aeroplane is flying at the height of 10 km above the ground the distance along the ground from the aeroplane to the airport is 10√3 km

The angle of depression will be calculated as the angle between the horizontal and the height of the plane as shown in the figure below.

As we know that the perpendicular theta is height and the base ratio is angle tan theta.

tanФ = Height / Base

tanФ  = 10 / 10 √3

tanФ = 1 / √3

Ф = tan⁻¹( 1 / √3 ) = 30°

Therefore the angle of depression from the aeroplane to the ground​ will be 30 degrees.
