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.

An architect designs a wheelchair ramp for a historical building. The entry way is a level platform at the top of stairs that are 3 meters above ground level and extend 4 m out from the building. There is an obstacle 25 m from the stairs, and the city code for ramps limits the incline angle to 6º. Is there sufficient distance for a ramp within this limit? How do you know? O Yes, because the ratio of O No, because the ratio of O No, because the ratio of is less than tan 6º. is greater than sin 6º. is greater than tan 6º. O Yes, because the ratio of is less than sin 6º.
Q7. A cellphone transmitter is placed at the top of a vertical tower. Cables are used to help support the tower. One end of a cable is anchored to the ground, and the other end is attached to the top of the tower. The two supporting cables are anchored to the ground at points A and B, which are 12 m apart. The angle between the ground and the cable anchored to points A and B is 62° and 72° respectively. Determine the height of the tower. Round your final answer to the nearest meter.
