To find the height of a tree, a person walks to a point 43 feet from the base of the tree. He moasures an angle of 60" between a line of sight to the top of the tree and the ground, as shown in Figure. Find the height of the tree. (Note : sin 60° - V3 , Cos 60" = and tan 60 = V3). O 43 feet O 4V3 feet ov3 feet O432 feet O 43/3 feet

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.
