A 100N uniform ladder, 8.0m long, rests against a smooth vertical wall. the coefficient of static friction between ladder and the floor is 0.40. What minimum angle can the ladder make with the floor before it slips?

im thinking 100*0.40=40 degrees? can someone tell me if this is right or give me the formula as to how to get it right?
