Question

if tan beta=3 then 4 sin beta -3 cos beta/4sin beta+3 cos beta ​

Answer 1

Step-by-step explanation:

tan beta =3

4 sin beta -3 cos beta / 4sin beta +3 cos beta

or, 4 sin beta /4cos beta -3 cos beta/4cos beta / 4sin beta /4 cos beta+3 cos beta/4 cos beta

or, 4tan beta-3/4 / 4tan beta+3/4

or, 3-3/4/3+3/4

or, 9/4× 4/15

or, 3/15
