You can put this solution on YOUR website! A flag pole is held upright by 30 metre long wire to the ground. If the wire makes an angle of 25 degrees to the ground. The hypotenuse is 30.How high is the flag pole?
----
Draw the picture:
You have a right triangle with:
hypotenuse = 30 m
height = flag pole.
angle at ground = 25 degrees
----
sin(25 degrees) = height/hypotenuse
----
height = 30*sin(25) = 12.68 meters
