A 13 foot ladder is leaning against a house when it’s base starts to slide away . By the time the base is 5 ft from the house, the base is moving away at the rate of 24 ft/sec. What is the rate of change of the height of the top of the ladder and at what rate is the area of the triangle formed by the ladder,wall, and ground changing then

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.
