A woman standing on a large rock at the edge of a lake is getting ready to swing from a rope that is tied to a branch that hangs over the water. The length of the rope the woman is holding is 8.3 m long. The woman hopes to land in the water at a point that is 13.3 m away from where she stands on the large rock. The angle between the point where the rope is tied and her landing spot in the water is 85°. What is the distance between the the point where the rope is tied and the point where she wants to land to the nearest tenth of a metre.
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.
