A laffer leaning against a house maes an angle of 60 degress with the ground. The foot of the leadder is 7 feet from the foundation of the house. How long is the ladder? Please help.
Draw a rt. triangle. The ladder is the
hyp. and the hor side is 7ft. The angle
between the hor side and the hyp is 60
deg.
hyp=7 / cos60=14ft = length of ladder.
