A person walks out an unknown distance from a building of height 18 m and shines a flashlight bea towards its top. He finds that when the beam is elevated at an angle of 37° with respect to the horizontal, the light strikes the top of the building. Find (i) the distance walked by him and (ii) the distance the flash light beam has to travel before it strikes the top of the building.

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.
