17. When the angle of elevation to the Sun is 69', a tower casts a shadow on the ground that is 64.3 feet long. sin 65 = 0.9063 sin 69 = 0.9336 cos 69 = 0.3584 cos 65 = 0.4226 tan 69 = 2.6051 tan 65 = 2.1445 Tower Shadow R Use the information in the table to determine the approximate length of the shadow cast by the tower when the angle of elevation to the Sun is 65°. A. 52.9 ft B. 54.5 ft C. 66.2 ft D. 78.1 ft
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.
