Question:

If $5 \sin \theta=4$, then the value of $\frac{\sec \theta+4 \cot \theta}{4 \tan \theta-5 \cos \theta}$ is:

Options:

2

$\frac{3}{2}$

$\frac{5}{4}$

1

Correct Answer:

2

Explanation:

sinθ = \(\frac{4}{5}

By using pythagoras theorem ,

P² + B² = H²

4² + B² = 5²

B² = 25 - 16

B² = 9

B = 3

Now,

\(\frac{ secθ + 4cotθ }{4tanθ - 5cosθ}\)

= \(\frac{ 5/3  + 4 × 3/4 }{4× 4/3 - 5×3/5}\)

=  \(\frac{ 5/3  + 3 }{16/3 - 3}\)

=  \(\frac{ 14 }{7}\)

= 2
