यदि $\sin \theta  = \frac{{24}}{{25}} $ हो और $\theta $ द्वितीय चतुर्थांश में है, तब $\sec \theta  + \tan \theta  = $  

A

$-3$

B

$-5$

C

$-7$

D

$-9$

Solution

(c) $\sin \theta = \frac{{24}}{{25}} $

$\Rightarrow \cos \theta = \frac{{ – 7}}{{25}},\,\tan \theta = \frac{{ – 24}}{7}$

$\therefore$  $\sec \theta  + \tan \theta  = \frac{{ – 25}}{7} + \frac{{ – 24}}{7} =  – 7$
