Problema Solution
A 25foot extension ladder leaning against a building makes a
68.2degrees° angle with the ground. How far up the building does the ladder​ touch?
Answer provided by our tutors
Let 'h' represent the height where the ladder touches the building.
The ladder, the ground and the building make a right triangle.
sin(68.2) = h/25
h = 25*sin(68.2)
h = 23.21 ft approximately
The ladder goes 23.21 feet up the building.
