  1. Correct Answer – b
    `sin^(2)1+sin^(2)11^(@)+sin^(2)21^(@)+sin^(2)31^(@)+sin^(2)41^(@)+sin^(2)45^(@)+sin^(@)49+sin^(2)59^(@)+sin^(2) 69^(@)+sin^(2)79^(@)+sin^(2)89^(@)`
    `rArr(sin^(2)79^(@))+sin^(2)89^(@))+(sin^(2)11^(@)+sin^(2)8=79^(@) )+(sin^(2)21 ^(@)+sin^(@)69^(@))+(sin^(2)31^(@)+sin^(2)59^(@))+(sin^(2)41^(@)+sin^(2)49^(@))+sin^(2)45^(@)`
    `rArr1+1+1+1+(1)/(2)`
    `(sin^(2)A+sin^(2)B=1`
    if `A+B=90^(@))rArr5(1)/(2)`
