You are flying a kite and have let out 30ft of string but it got caught in a 8ft tree. What is the angle of elevation to the location of the kite?
This is a right triangle> the string is the hypotenuse the tree is one leg and the distance from you to the tree is the other leg.
S-O-H C-A-H T-O-A S-O-H sin = opposite over hypotenuse = 8/30
sin= 8/30
arcsin (8/30) = 15.47 degrees
