Answer 2

Answer:

$\tan(\theta) = \frac{4}{3}$

Step-by-step explanation:

Given =

${ \sin } ( \theta ) = - \frac{ 4}{5} \\ \cos(\theta) = - \frac{ 3}{5}$

We know that,

$\tan(\theta) = \frac{ \sin(\theta) }{ \cos(\theta) }$

$= \frac{ - \frac{4}{5} }{ - \frac{3}{5} }$

$= - \frac{4}{5} \times ( - \frac{5}{3} )$

$= \frac{20}{15}$

$= \frac{4}{3}$
