Step-by-step explanation:
Area of the shaded region = area of the outer square - area of the inner square
= 22×22 - 15×15 sq ft
= 484 - 225 sq ft
= 259 sq ft
ROC is often used when speaking about momentum, and it can generally be expressed as a ratio between a change in one variable relative to a corresponding change in another; graphically, the rate of change is represented by the slope of a line. The ROC is often illustrated by the Greek letter delta.

The angle of depression from the bird to the observer is 41.81°
<h3 />
<h3>Angle of depression</h3>
The angle of depression can be calculated using trigonometric ratios. The situation forms a right angle triangle. A right angle triangle has opposite , adjacent and hypotenuse side.
Using trigonometric ratio,
- sin B = opposite / hypotenuse
Therefore,
sin B = 6000 / 9000
sin B = 0.66666666666
B = sin⁻¹ 0.666666
B = 41.8103143833
B ≈ 41. 81°
