Question

help me with this.. please ​

Answer 1

$\frac{ \sin {}^{2} 73 + \sin {}^{2} 17}{ \cos {}^{2}28 + \cos {}^{2} 62} \\ \frac{ \sin {}^{2} 73 + \sin {}^{2}(90 - 73) }{ \cos {}^{2} 28 + \cos {}^{2}(90 - 28) } \\ \frac{ \sin {}^{2} 73 + \cos {}^{2} 73}{ \cos {}^{2}28 + \sin {}^{2} 28} \\ \frac{1}{1} \\ 1$

I hope that helps you dear .........
