Answer 185.6 meters from the base of the tower Explanation Given information: Fire Fighting: A fire is sighted from a fire tower in Wayne National Forest in Ohio. The ranger found that the angle of depression to the fire is 22 ∘ . Calculation: The angle be measure is opposite the tower and we imagine it was built perpendicular to the ground, so TOA in SOHCAHTOA ... tan 22 ∘ = 75 x x = 75 tan 22 ∘ x ≈ 185.6 Thus, 185.6 meters from the base of the tower

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.
