Question

Which of the following is the same as $\sec 53$?

• A. $\tan 37$
• B. $\text{cosec}37$
• C. $\sec 37$
• D. $\cos 37$

Answer 1

The correct option is B $\text{cosec}37$

We know that,
$\sec \theta =\text{cosec}(90-\theta )$

$\begin{array}{cc}\sec 53& =\text{cosec}(90-53)\\ & =\text{cosec}37\end{array}$
