If cos `(40+x)^@ =sin 30^@`, find the value of x.

Find x if :- if cos (40+x)= sin30^@ . Find the value of x.

If cos(40^@ +x) =sin30^@ then the value of x is ___

If cos(40-x)=sin30 ,find the value of x

If cos(40^@+A)=sin 30^@ , then the value of A is

If sin x = sin 60^(@) cos 30^(@)- cos 60^(@) sin 30^(@) , then the value of x is

If sin (x - 20)^(@) = cos (3x - 10)^(@) , then find the value of x.

If cos 2x = cos 60^(@) cos 30^(@) + sin 60^(@) sin 30^(@), then the value of x is

If x sin30^@ cos60^@= sin45^@. cos45^@ , then the value of x is: यदि x sin30^@ cos60^@= sin45^@. cos45^@ तो x का मान है:

If 2cos x+sin x=1, then find the value of 7cos x+6sin x
