   A guy wire fastened 50 m from the base of a tower makes an angle of 55 degrees with the ground.     

   How high up is the tower does the guys wire reach?     

 

   tangent  =  opposite over adjacent     

 

   tan(55^o)  =  height / 50     

   1.4281    =  height / 50     

   height     =  (50) (1.4281)     

   height     =   71.405 rounds to 71.4 m
