Question 765786: A ladder leaning against a wall makes a 60 degrees angle with the ground. The base of the ladder is 4m from the building. How high above the ground is the top of the ladder?

Right angled triangle.
Base = 4m
Angle with ground = 60 degrees
Height of top of ladder is found by
tan = Opposite/Adjacent
tan (60) = Opposite/4
Opposite = 4 + tan(60) = 6.9m
This is the height of the top of
ladder above ground.
Hope this helps.
