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∘, degree . What is the width of the river?

Hoi mate heres your answer
Answer:
width of the river is 60.16 m
Step-by-step explanation:
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
hope it help and also mark me as the brainiest
Answer:
yes it is 100 and 10 % 60.16
Step-by-step explanation:
I was doing Kahn academy and I thought his answer was wrong because he sounded like a pirate so I went with the other answer and said I was wrong but then I chose this answer at 60.16 and got it right. so I took one for the team to figure this out so pls put this answer especially if you are doing Kahn academy in the middle of the night because you are not the best at math or just cant do math and trying to get it from online and your big fat polish geometry teacher doesn't yell at you. yes I'm talking about you miss Jankowska. so any ways pls give me a heart and a 5 star.
Thank you
ps. if your wondering what school miss Jankowska is in she is in palm harbor Florida at palm harbor middle school and I'm joseph Avery at period 4
remember to hit the heart PLS and 5 stars PLEASE
THANKYOU AGAIN.
