• B) \(\tan ( s + t ) = - \frac { 1 } { 21 }\) \(\tan ( s - t ) = \frac { 9 } { 19 }\)
• C) \(\tan ( s + t ) = - \frac { 19 } { 9 }\) \(\tan ( s - t ) = \frac { 21 } { 1 }\)
• D) \(\tan ( s + t ) = \frac { 5 } { 6 }\) \(\tan ( s - t ) = - \frac { 5 } { 6 }\)
• E) \(\tan ( s + t ) = - \frac { 21 } { 1 }\) \(\tan ( s - t ) = \frac { 19 } { 9 }\)
