In the right triangle ABC, AB = 2, BC = 4 and ED is a line parallel to AB. Find the angle α = angle BAD which minimizes the distance L, where L = AD + ED
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.
Solve the ff. problems using trigonometric or inverse trigonometric functions. Show illustration, define variables used and give a detailed solution.
