Two vertical poles , 3m and 7m long are on the same straight line with point P on the ground.The shorter pole is 20m from P and is between P and the longer pole .The angle of elevation of the top T of the longer pole from the top R of the shorter one is 30 degrees Calculate the length of RT and the horizontal distance from P and the longer pole
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.
