Heya ❗
here's Ur answer ❗

= sin ⊘ = cos (90 - ⊘)

= cos { 90 - (x - 2y)] = cos (4y - x)

= 90 - (x - 2y) = 4y - x

= 90 - x + 2y = 4y - x

Hello Friend..❤️❤️

The answer of u r question is..✌️✌️

If sin(x+2y)=cos (4y-x)

Sin tita = cos(90-tita)

cos[90-(x-2y)]=cos4y-x

=90-(x-2y)=4y-x

=90-x+2y=4y-x

Hence proved.
