Problema Solution
A ladder leaning against a hose makes an angle of 60° with the ground. The foot of the
ladder is 7 feet from the foot of the house. How long is the ladder?
Answer provided by our tutors
Let 'x' represent the length of the ladder.
cos(60) = 7/x
x = 7/cos(60)
x = 7/0.5
x = 14 ft
The ladder is 14 feet long.
