Problema Solution
A20 foot ladder leans against a wall so that the base of the ladder is 8 feet from the base of the building. What angle does the ladder make with the ground?
Answer provided by our tutors
Solution:the ladder is 20 foot, and distance between ladder and building is 8 foot, so this forms a right triangle,
Set the angle is X
So the cosine rate is cos X = 8/20 =0.4, X = 66.4°
The Angle is 66.4° between ladder and ground
