If sin theta = -5/7 , which of the following are possible?

Sav [38]

Solution:

we are given that

$sin \theta=-5/7$

As we know that

$cos \theta =\sqrt{1-sin^2 \theta} \\$

Substitute the value we get

$cos \theta=\sqrt{1-(\frac{-5}{7})^2} \\
\\
cos \theta=\sqrt{1-(\frac{25}{49})} \\
\\
cos \theta=\sqrt{(\frac{24}{49})} =\frac{\sqrt{24}}{7}\\$

Since $sec \theta=\frac{1}{cos \theta}\\$

So here $sec \theta=\frac{7}{\sqrt{24}}\\$

As we know that

$tan \theta=\frac{sin \theta}{cos \theta}\\
\\ \text{Substitute the values we get}\\
\\
tan \theta=\frac{-5/7}{\frac{\sqrt{24}}{7}}\\
\\
tan \theta=\frac{-5}{\sqrt{24}}\\$

Hence the correct option is C.
