The distance between the helicopter and the first home is 369. 87 m
<h3>How to solve the distance using the angle of depression?</h3>
The distance between the helicopter and the first home can be found using sine law,
Therefore,
180 - 72 - 49 = 59 degrees.
Hence,
420 / sin 59 = A / sin 49°
where
A = distance form the first home to the helicopter.
cross multiply
420 sin 49 = A sin 59°
A = 420 sin 49 / sin 59
A = 316.978023694 / 0.8571673007
A = 369.869339199
A = 369. 87 m

The Area of the fabric required is 3.6 square feet
The square's side length is 3 feet.
Due to the fact that Lin is creating a window covering for a window that is half circle-shaped on top of a square.
The window covering must therefore be a semicircle with a 3-feet diameter.
thus the semicircle's radius is equal to d/2 = 3/2 feet
Now, the Area of the semicircle,
Putting the value of the radius in the equation, we have,
Hence, The Area of the fabric required = 3.6 square feet
