    Use the above triangle to find  cosB\cos B  ,  tanB\tan B  , and  sinB\sin B  

     cosB=1517, tanB=158, sinB=817\cos B=\frac{15}{17},\ \tan B=\frac{15}{8},\ \sin B=\frac{8}{17}  

     cosB=817, tanB=158, sinB=1517\cos B=\frac{8}{17},\ \tan B=\frac{15}{8},\ \sin B=\frac{15}{17}  

     cosB=1517, tanB=815, sinB=817\cos B=\frac{15}{17},\ \tan B=\frac{8}{15},\ \sin B=\frac{8}{17}  

     cosB=815, tanB=817, sinB=1517\cos B=\frac{8}{15},\ \tan B=\frac{8}{17},\ \sin B=\frac{15}{17}
