Question

o If A=45 tan B=2/5 find tan (A-B). ​

Answer 1

Answer:

$\tan(a - b) = \frac{3}{7} .$

Step-by-step explanation:

$\tan(a) = 1 \\ \\ \tan(b) = \frac{2}{5} \\ \\ \tan(a - b) = \frac{ \tan(a) - \tan(b) }{1 + \tan(a) \tan(b) } \\ \\ = \frac{1 - \frac{2}{5} }{1 + (1)( \frac{2}{5}) } \\ \\ = \frac{ \frac{3}{5} }{ \frac{7}{5} } \\ \\ = \frac{3}{7} .$
