Question

Sin theta =7/25 cosec theta

Answer 1

Answer:

$cos \theta = \frac{24}{25}$

Step-by-step explanation:

${ \sin }^{2} \alpha + { \cos }^{2} \alpha = 1$

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

$c = \sqrt{1 - {( \frac{7}{25} })^{2} }$

$c = \sqrt{1 - \frac{49}{625} }$

$c = \sqrt{ \frac{576}{625} }$

$c = \frac{24}{25}$
