A radio tower, DC, has a support wire 113 feet in length attached to the top at point C and to the ground at point A where it makes a 47 o angle with the ground (angle CAB). A second wire is to be added which runs from point C to point B on the ground. This wire will be attached at point B 20 feet from point A. 2a) Determine the length required for the 2nd wire from point B to point C. Round your answer to one decimal place. 2b) Determine the measure of the angle ABC. (Note: Look at the figure when determining your answer.) Round your answer to one decimal place.
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.
