Answer 1

$\red { Value \: of \: \Big(\frac{sin 27\degree}{cos 63\degree}\Big)^{2} + \Big(\frac{cos 63\degree}{sin 27\degree}\Big)^{2}}$

$= \Big(\frac{sin 27\degree}{cos (90 - 27\degree)}\Big)^{2} + \Big(\frac{cos 63\degree}{sin (90 - 63\degree}\Big)^{2}$

$= \Big(\frac{sin 27\degree}{sin 27\degree}\Big)^{2} + \Big(\frac{cos 63\degree}{cos 63\degree}\Big)^{2}$

$= 1 + 1 \\= 2$

Therefore.,

$\red { Value \: of \: \Big(\frac{sin 27\degree}{cos 63\degree}\Big)^{2} + \Big(\frac{cos 63\degree}{sin 27\degree}\Big)^{2}} \green {= 1 }$
