Question:

If $cot θ=\frac{80}{39}$, find the value of cosec θ.

Options:

$\frac{39}{80}$

$\frac{89}{39}$

$\frac{39}{89}$

$\frac{89}{80}$

Correct Answer:

$\frac{89}{39}$

Explanation:

cotθ =  \(\frac{80 }{39}\)

{ cotθ =  \(\frac{B }{P}\) }

P² + B² = H²

39² + 80² = H²

H = 89

Now,

cosec θ

= \(\frac{H }{P}\)

= \(\frac{89 }{39}\)
