Answer 1

HELLO DEAR,

GIVEN:-
$\sf{cot\Theta = \frac{7}{8}}$

( 1 ). $\sf{\frac{(1 + sin\Theta)(1 - sin\Theta)}{(1 + cos\Theta)(1 - cos\Theta)}}$

$\sf{\Rightarrow \frac{1 - sin^2\Theta}{1 - cos^2\Theta}}$

$\sf{\Rightarrow \frac{cos^2\Theta}{sin^2\Theta}}$

$\sf{\Rightarrow cot^2\Theta}$

$\sf{\Rightarrow (\frac{7}{8})^2 =\frac{49}{64}}$

I HOPE ITS HELP YOU DEAR,
THANKS
