Note  cos B  = adjacent side  / hypotenuse  = a / c

 

So

 

cos B   = 6 / 11

 

Take the arccos  (cosine  inverse) to find  B

 

arccos   (6/11)  = 56.944268849146°

 

Degrees  =  56

Minutes  = 60 * .944268849146   =  56.65613094876  =   57 minutes

 

So

 

B  = 56° 57'

 

 

cool cool cool
