1.	Evaluate : `(2sin^2 63^@+1+2sin^2 27^@)/(3 cos ^2 17^@-2+3cos^2 73^@)`A. `(3)/(2)`B. `(2)/(3)`C. 2D. 3
Answer» Correct Answer - D Given expression `=(2(sin^(2)63^(@)+sin^(2)27^(@))+1)/(3(cos^(2)17^(@)+cos^(2)73^(@))-2)=(2(sin^(2)63^(@)+cos^(2)63^(@))+1)/(3(cos^(2)17+sin^(2)17^(@))-2)` `=((2xx1)+1)/((3xx1)-2)=3. " " \|(because sin27^(@)=sin(90^(@)-63^(@))=cos63^(@)),(cos73^(@)=cos(90^(@)-17^(@))=sin17^(@))\|`
