Answer:
D) 22534 m
Step-by-step explanation:
<em>The figure forms a Z shape where the top line and bottom line are parallel. Therefore the angle with the coastline, inside the triangle will be 16.5°.</em>
<em>We have to find the hypotenuse which is the side opposite to the 90 degree angle.</em>
<em>Now this can be solved through sin formula</em>
<u>Step 1: Write all the data</u>
Angle = 16.5°
Opposite = 6400
Hypotenuse = ?
<u>Step 2: Use the sin formula</u>
Sin (Angle) = Opposite/Hypotenuse
Sin (16.5) = 6400/Hypotenuse
<u>Step 3: Solve</u>
Hypotenuse = 6400/sin(16.5)
Hypotenuse = 22533.99 rounded off to 22534 m
The jet has to fly 22534 m before it reaches the coastline.
Therefore, option D is the correct answer.
