4. Alayna is trying to determine the angle at which to aim her sprinkler nozzle to water the top of a ft bush in her yard. Assuming the water takes a straight path and the sprinkler is on the ground 4 f from the tree, at what angle of inclination should she set it?
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.
