Answer 2

$\bold \red \star \: \underline{Given:-}$

$\tt{ \sin(90 \degree - A) \: \: is}$

$\rule{200}2$

$\\ \\ \bold \red \star \: \underline{Solution:-}$

$\tt{ \: \: \: \: \: \sin(90 \degree - A)} \\ = \tt \red{ \cos A.}$

$\rule{200}2$

$\\ \\ \bold \red \star \: \underline{Some \: \: Information:-}$

$\tt {\sin(90 \degree - \theta) = \cos \theta. }\\ \\ \tt{ \cosec(90 \degree - \theta)} = \sec \theta. \\ \\ \tt{ \tan( 90\degree - \theta) = \tan \theta. }$
