A kite is on a 25 m string. The kite is directly above a barn that is 18 m away from the person holding the kite string. What angle does the string make with the ground?     

 

cosine = adjacent over hypotenuse     

 

cosine  =  18 / 25     

cosine  =  0.7200     

 

arccosine (0.7200)  =  43.95^o
