Question:

If $sin\theta =\frac{8}{17}$ where θ is an acute angle, then what is the value of tan θ + cot θ ?

Options:

$\frac{217}{110}$

$\frac{281}{190}$

$\frac{289}{120}$

$\frac{512}{321}$

Correct Answer:

$\frac{289}{120}$

Explanation:

We are given that :-

sin θ = \(\frac{8}{17}\)

{ we know, sinθ = \(\frac{P}{H}\) }

By using pythagoras theorem,

P² + B² = H²

8² + B² = 17²

B = 15

Now,

tan θ + cot θ

= \(\frac{P}{B}\) + \(\frac{B}{P}\)

= \(\frac{8}{15}\) + \(\frac{15}{8}\)

= \(\frac{289}{120}\)
