Question 467845: A cable 20 feet long connects the top of a flagpole to a point on the ground that is 16 feet from the base of the pole. How tall is the flagpole? (A). 8ft. (B). 10ft. (C). 12ft. (C). 26ft Answer by mananth(16946) (Show Source):
You can put this solution on YOUR website! The rope,ground line and the pole form a right triangle
Leg 1 = 16 ft
Hypotenuse = 20 feet
Leg 2 is the distance from foot of pole to the point the rope is tied = x
20^2-16^2= x^2
400-256=x^2
144 = x^2
take the square root
x= 12 feet
