sin^25+sin^265+?3(tan5 . tan15 . tan30 . tan75 . tan85

Dear student,

Assuming your question to be as follows :

$\sin^{2} 25^{0} + \sin^{2} 65^{0} + \sqrt{3} (\tan 5^{0} \tan 15^{0} \tan 30^{0} \tan 7 5^{0} \tan 85^{0}) = \sin^{2} 25^{0} + {(\sin 65^{0})}^{2} + \sqrt{3} (\tan 5^{0} \tan 15^{0} \frac{1}{\sqrt{3}} \tan 7 5^{0} \tan 85^{0}) = \sin^{2} 25^{0} + {(\sin (90^{0} - 25^{0}))}^{2} + \sqrt{3} \times \frac{1}{\sqrt{3}} (\tan 5^{0} \tan 15^{0} \tan 7 5^{0} \tan 85^{0}) = \sin^{2} 25^{0} + \cos^{2} 25^{0} + (\tan (90^{0} - 85^{0}) \tan (90^{0} - 75^{0}) \tan 7 5^{0} \tan 85^{0}) (\sin^{2} θ + \cos^{2} θ = 1) = 1 + (\cot 7 5^{0} \cot 85^{0} \tan 7 5^{0} \tan 85^{0}) = 1 + \frac{\tan 7 5^{0} \tan 85^{0}}{\tan 7 5^{0} \tan 85^{0}} (\cot θ = \frac{1}{\tan θ}) = 1 + 1 = 2 H e n c e, \sin^{2} 25^{0} + \sin^{2} 65^{0} + \sqrt{3} (\tan 5^{0} \tan 15^{0} \tan 30^{0} \tan 7 5^{0} \tan 85^{0}) = 2$
