Answer:
<em>The height of the plane is 405 meters</em>
Step-by-step explanation:
<u>Trigonometric Ratios</u>
The situation can be represented as shown in the image below. The ground, the height H, and the direct distance to the plane to the shipwreck form a right triangle, where the trigonometric ratios stand.
Since the known distance is adjacent to the angle, and the required height is opposite to the given angle, we use the tangent ratio, defined as:
We need to find H, so we solve for H:
H=405 m
The height of the plane is 405 meters
