Answer 2

$\boxed{\huge\mathsf{question}}$

$\huge{\frac{ {sin}^{2} 63 + {sin}^{2} 27}{ {cos}^{2} 17 + {cos}^{2} 73}}$

$\boxed{\huge\mathsf{answer}}$

$\huge{ \frac{ {sin}^{2} 63 + {sin}^{2} 27}{ {cos}^{2} 17 + {cos}^{2} 73}}$

$\rightarrow \: \huge{\frac{ {sin}^{2} 63 + {sin}^{2} (90 - 63)}{ {cos}^{2} (90 - 73)+ {cos}^{2} 73}}$

$\rightarrow \: \huge{ \frac{ {sin}^{2} 63 + {cos}^{2} 63}{ {sin}^{2} 73+ {cos}^{2} 73}} \\ (since \: { \: {sin}^{2} \: or \: cos}^{2}(90 - x)= x)$

$\huge{we \: know \: \\ {sin}^{2} x + {cos}^{2} = 1 \\ then \: using \: this \: formula \\ \: we \: get}$

$\huge{\rightarrow \: \frac{1}{1} = 1}$
