Question
Louise is painting around a window frame in the outside of her house. Her ladder is 3.5m long and she placed it 1.0m from the house.
a) What is the slope of the ladder?
b) if she wants to follow the 1 in 4 rule, is this ladder safe?
** I got 3.5 m for question a ,but not sure if it’s correct and I don’t have a clue how to do b. Any help is appreciated. Thank you.

cosine of the slope angle is ... 1 / 3.5
not sure about (b) ... but base to height makes sense
... anything less than 1:4 is probably unsafe
