A steel girder 27 feet long is to be moved on rollers along a passageway 8 feet in width and into a corridor at right angles to the passageway. If the horizontal width of the girder is neglected, how wide must the corridor be in order that the girder can go around the corner?
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.
