The people of Bridgetown wanted to build a bridge across a nearby river. Since they were poor swimmers, their master Trigonomos agreed to measure the width of the river without actually crossing it. Trigonomos spotted a tree across the river and marked the spot directly across from it. Then he walked to another point 15 meters down the river and found that the angle between his side of the river and the line connecting him to the tree was 76°. What is the width of the river? Round your final answer to the nearest hundredth The width of the river is 60.16 meters. The width of the river is 14.55 meters. The width of the river is 10.30 meters. The width of the river is 72.24 meters

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.
