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 1 5 1515 meters down the river and found that the angle between his side of the river and the line connecting him to the tree was 7 6 ∘ 76 ∘ 76, degree. what is the width of the river? round your final answer to the nearest hundredth.

width of the river is 60.16 m

Step-by-step explanation:

Refer the attached figure

AB = width of river

We are required to find the width of river .

Since we are given that . Trigonomos spotted a tree across the river and marked the spot directly across from it.

Then he walked to the another point  15 meters down the river .i.e. BC = 15 m

He also found the angle between his side of the river and the line connecting him to the tree  i.e. ∠ACB = 76°

So, now to calculate the width of river i.e. AB , we will use trigonometric ratio

Thus the width of the river is 60.16 m
