Answer:
Step-by-step explanation:
You already know the area, so just reverse the steps. Example: 200ft divided by the length which is 16ft equals 12.5 feet
The sum of the interior angles of any triangle is 180 degrees. It does not depend on which triangle we are discussing that this fact is true for all triangles. 180 degrees is a straight line.
Answer:
the submarine is 92.994 feet ≈ 93 feet deep from the surface of the water
Step-by-step explanation:
We can think in a triangle where the hypotenuse is the detection distance and the angle with the horizontal surface of water is the depression angle, then the underwater distance is the vertical side of the triangle.
If we denote Ф as the angle of depression ,d as the detection distance and x as the unknown depth of the submarine, using trigonometry:
x = d* sin Ф
thus
x= d * sin Ф = 238 feet * sin 23° = 92.994 feet ≈ 93 feet
