Choose the correct answer in each of the following questions: If tan^(2)45^(@)-cos^(2)30^(@)=x sin45^(@) cos 45^(@) " then " x =?

If tan^(2) 45^(@)-cos^(2) 60^(@)=x sin 45^(@) cos45^(@) tan 60^(@) , then find the value of x.

4sin^(2)60^(@)+3tan^(2)30^(@)-8sin45^(@)*cos45^(@)

If tan^2 45^@-cos^2 30^@=xsin45^@ \ cos45^@ , then x is (a) 2 (b) -2 (c) -1/2 (d) 1/2

Evaluate sin45^(@)+cos45^(@)

If a sin45^(@).cos45^(@).tan60^(@)=tan^(2)45^(@)-cos60^(@) , then find the value of a .

If tan^(2)45o-cos^(2)30o=x sin45o cos450 then x=(a)2(b)-2(c)-(1)/(2)(d)(1)/(2)

If x sin45^(0)cos^(2)60^(@)=(tan^(2)60^(@)cos ec30^(@))/(sec45^(@)cot^(2)30^(@)) then x=
