A wire is atteched to the top of a 10 metere?
A wire attached to the top of a 10meter tall falgpole and forms a 60 degree angle with the ground. how long is the wire??
Answer:
L = length of wire which is the hypotenuse of the triangle formed.
sine 60 degrees = 10/L since sine is opposite over hypotenuse
so solving for L gives L = 10/sin(60)= 10/{sqrt(3)/2}=20/sqrt(3)
So L is about 11.55 meters ie length of wire.
i dont know and dont care 75 m
It's a 30-60-90 right triangle, which is half of an isosceles triangle. This means that the two legs of the triangle are the same height - representing the height of the flagpole and the distance to the place where the wire hits the ground - they are both 10m.
This means you have a 1 1 root2 type right triangle.
The hypotenuse = length of the wire = 10*root2 = 14.14m.
Russell is correct in his approach. The length of the cable is 11.547 meters.
