Answer 1

Answer:

11/26

Step-by-step explanation:

3 tanθ = 4

3 sinθ/cosθ = 4

3 sinθ = 4 cosθ

sinθ = 4/3 cosθ

(5sinθ - 3cosθ )/(5sinθ + 2cosθ )

=(5*4/3 cosθ - 3cosθ )/(5*4/3 cosθ + 2cosθ )

= (20cosθ - 9cosθ)/3 * 3/(20cosθ + 6cosθ)

= 11cosθ / 26cosθ

=11/26

Answer 2

3 tan A = 4

tan A = 4/3

tan A = p/b

Therefore p = 4

b = 3

So, h = 5 ( By Pythagorous)

Now,

sin A = 4/5

cos A = 3/5

Put the values in equation and after solving eqn we get 11/26.
