A ladder is leaning against a building and makes 32° angle with the ground. The top of the ladder reaches 20 feet up on the building. What is the length of the ladder?

The ladder is the hypotenuse of a right triangle      One leg is 20 feet   

 

sin = opp / hyp  

sin 32 = opp /hyp

hyp = opp/sin32 =  37.74 ft
