Haley planted a new tree in her yard. To help the tree to grow upright, she attached support wires to the tree. If the support wires are each attached 4 ft up the tree and form a 56° angle with the ground, what is the length of each support wire? sin 56° ≅ 0.83 cos 56° ≅ 0.56 tan 56° ≅ 1.48
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.
