1. The problem statement, all variables and given/known data

"A ladder of weight 200n and of length 5m rests with its lower end on a horizontal rough concrete surface and its upper end against a smooth wall. if the ladder just starts to slip when the angle between it and the concrete is 40(degrees) calculate the coefficient of static friction:"

having trouble with trigonometry here, i can do questions where i have lengths but no angle but this one is spinning me out.
