a boat is pulled towards the dock with the help of a crane. The winch was placed at the end of the dock and the boron traction rope was attached to the bow of the boat at a level of 10 ft. the rope is pulled at a constant speed of 1ft / sec. Using an inverse trigonometric function, what is the elevation angle of the rope since the difference between the end of the boat and the end of the dock is 30ft?
Ratios
A ratio is a comparison between two numbers of the same kind. It represents how many times one number contains another. It also represents how small or large one number is compared to the other.
Trigonometric Ratios
Trigonometric ratios give values of trigonometric functions. It always deals with triangles that have one angle measuring 90 degrees. These triangles are right-angled. We take the ratio of sides of these triangles.
