$if \: 5 \sin( \alpha ) = 4 \cos( \alpha ) then \: \tan( \alpha ) =$
$a. \frac{4}{5} \: b.5 \: \: c.4 \: \: d. \frac{5}{4}$
​

Answer 1

HEY ÁÑSHU HERE IS YOUR ANSWER-

=) SIN= 4

=) COS= 5

AND WE KNOW THAT

$\tan = \frac{ \sin }{ \cos }$

putting VALUE of sin and cos

$\tan( \alpha ) = \frac{4}{5}$

OPTION (A) IS CORRECT

Answer 2

Here is your answer my behna ^_^

$\underline\bold{\huge{Answer !!}}$

$5 \: sin \: \alpha = 4 \: cos \: \alpha \\ \\ = > \frac{sin \alpha }{cos \alpha } = \frac{4}{5} \\ \\ = > tan \: \alpha = \frac{4}{5}$

OPTION (A) is correct answer.
