the proper angle for a ladder is about 75 degrees from the ground. suppose you have a 27 foot ladder. how far from the house should you place the base of the ladder?

Answer 1

Since you are looking for the base you are going to use cosine theta=a/h or cosine theta= a/27

We know cos(75) is approximately = .26

=27(.26)=7.02 ft. from the house

Hope this helps! (:
