Answer:
Step-by-step explanation:
ok, so you tangent is opposite/adjacent. You need to find the adjacent side. You could do a^2+b^2=c^2.A and B are the legs and c is the hypotunese. 85^2-77^2=b^2. This solves to b being 36. This means the adjacent side is 36 and opposite being 77. The tangent of Y is 77/36.
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

Step-by-step explanation:
Answer:
based on yahoo, cause my iq is like 10...the answer is B
Step-by-step explanation:
No because 4 square equals 2 square and since 3 isn't a perfect number, it would be 2 square times 3 square, which equals 6 square.
