Answer:
The length of the rope is 69.28m
Step-by-step explanation:
GIVEN:
height of the pole = 60m
angle of inclination at the rope = 60°.
TO FIND:
length of the rope
SOLUTION
As shown in the image given , the pole, the rope and the ground forms a right angle triangle. so, we can use trigonometry here to find the length of the rope.
If we take rope as hypotenuse, pole as perpendicular side and ground as base then with the given information we can use sine formula.
sin ∅= perpendicular side / hypotenuse
L = 69.28m
Hence the length of the rope is 69.28m
