(x^(2)+4a^(2)+4x^(2)+3a^(2)-3ax^(2)+5^(2))/(sin^(2)30^(@)+cos^(2)30^(@))

Evaluate the following: (v) (5cos^(2)60^(@)+4 sec^(2) 30^(@)-tan^(2)45^(@))/(sin^(2)30^(@)+cos^(2)30^(@))

Evaluate the following : (5cos^(2)60^(@)+4sec^(2)30^(@)-tan^(2)45^(@))/(sin^(2)30^(@)+cos^(2)30^(@))

The value of (cos^(2)60^(@)+4sec^(2)30^(@)-tan^(2)45^(@))/(sin^(2)30^(@)+cos^(2)30^(@)) is

(5cos^(6)60^(@)+4sec^(2)30^(@)-tan^(2)45^(@))/(sin^(2)30^(@)+cos^(2)30^(@))

Evaluate : ( 5 cos ^(2) 60^(@) + 4 sec ^(2) 30^(@) - tan ^(2) 45^(@))/( sin ^(2) 30^(@) + cos ^(2) 30^(@))

Q.Determine x if (x sin^(2)30^(@)cos^(2)60^(@))/(4cos^(2)45^(@))=(3sin^(2)45^(@)+2cos^(2)30^(@))/(sin^(2)90^(@)-4cos^(2)45^(@))

(5cos ^ (2) 60 ^ (@) + 4sec ^ (2) 30 ^ (@) - tan ^ (2) 40 ^ (@)) / (sin ^ (2) 30 ^ (@) + cos ^ ( 2) 30 ^ (@))

(5cos^(2)60+4sec^(2)30-tan^(2)45)/(sin^(2)30+cos^(2)30)
