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

Answer:
<h2><em><u>23</u></em><em><u> </u></em><em><u>days</u></em></h2>
Step-by-step explanation:
<em><u>Given</u></em><em><u>,</u></em>
No. of days taken by Jenny to read 7 books
= 8
<em><u>So</u></em><em><u>,</u></em>
No. of days taken by her to read 1 book

<em><u>Therefore</u></em><em><u>,</u></em>
No. of days taken by her to read 20 books

- <em>[</em><em>On</em><em> </em><em>Simplification</em><em>]</em>

- <em>[</em><em>On</em><em> </em><em>dividing</em><em>]</em>
= 22.85.....
- <em>[</em><em>On</em><em> </em><em>approximating</em><em>]</em>
= 23 days (approx. )
<em><u>Hence</u></em><em><u>,</u></em>
<em><u>Jenny</u></em><em><u> </u></em><em><u>will</u></em><em><u> </u></em><em><u>take</u></em><em><u> </u></em><em><u>23</u></em><em><u> </u></em><em><u>days</u></em><em><u> </u></em><em><u>to</u></em><em><u> </u></em><em><u>read</u></em><em><u> </u></em><em><u>20</u></em><em><u> </u></em><em><u>books</u></em><em><u> </u></em><em><u>(</u></em><em><u>Ans</u></em><em><u>)</u></em>
Answer:
50.4 km (Answer B)
Step-by-step explanation:
From this information, we are able to create a proportion, 2cm/21km= 4.8cm/x km (x representing the actual distance). After cross-multiplying and simplifying, you get an answer of 50.4km. Hope this helps!
