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,
Hence,
180 - 72 - 49 = 59 degrees.
Therefore,
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
Therefore, the distance between the helicopter and the first home is 369. 87 m

I hope this is correct!!
Answer:
12 3/8
Step-by-step explanation:
A = 2 3/4 x 4 1/2
best way is to change mixed numbers to fractions and multiply and then go back to a mixed number.
11/4 x 9/2 = 99/8 = 12 3/8
