Question

Suppose that you are watching the tree warden trim branches from a large tree in your yard. He has climbed up 15 meters and his assistant is holding a rope that will be used to guide the branch when it falls. To the nearest meter, how long is the rope?

Answer 1

90 - 55 = 35.
180-90-35 = 55 degrees. (angles in a triangle)
let x be the rope length.
\[\sin 90 degrees / x = \sin 55 degrees / 15\]

Answer 2

by using sine rule

Answer 3

sin55= 15/x

Answer 4

These are the answer choices
26
20
70
40

Answer 5

the ans should be 18?

Answer 6

to the nearest meter it is 18, but the nearest in your answer choices is 20. so go with that

Answer 7

Ok thank you very much guys.
