Question

HEYYYY! BRAINLY PEOPLE I HAVE A CHALLENGE FOR YOU . JUST SOLVE PLEASE .​

Answer 1

Step-by-step explanation:

1/cot=tan

then,

1/5÷12,=12/5.

so divide the equation by cos .

then, (5sin/cos-3cos/cos)/5sin/cos+3cos/cos

=(5tan-3)/(5tan+3)

=(5×12÷5-3)/(5×12÷5+3)

=(12-3)/(12+3)

=9/15

=3/5
