To find the equation perpendicular to the given line, we need to factorise it. Consider 2x2 - 5xy + 2y2 = 0.

Or, 2x2 - 4xy – xy + 2y2 = 0

Or, 2x(x - 2y) – y(x - 2y) = 0

Or, (x - 2y)(2x - y) = 0 x .....

Here, LHS =  Sin(60 - A) cos(60 - B)- cos(60 - A) sin(60 - B)  = Sin{60 - A - (60 - B)}  [ Since, sinX cosY - cosX sinY = sin(X - Y)] = Sin{60 - A - 60 + B} = sin{- A + B} = sin(B - A) = .....

Here,  LHS = SinA.sin(B-C) + sinB.sin(C - A) + sinC.sin(A - B)  Using formula of sin(A - B) and others, we get = SinA(sinB.cosC - cosB sinC) + sinB(sinC cosA - cosC sinA) + sinC(sinA cosB - cosA sinB) Opening the brackets, .....

We know,

cos A = cos (2A/3 + A/3)

= cos 2A/3. cos A/3 - sin 2A/3. sin A/3

= (2 cos2 A/3 - 1) cos A/3 - 2 sin A/3 cos A/3 ∙ sin A/3

= 2 cos3 A/3 - cos A/3 - 2 cos A/3 (1 - cos2A/3)
