cos(40+x)=sin30" the the value "1x

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

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

If cos (x-y)+1=0, then the value of (cos x+ cos y) and (sin x+sin y) is-

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

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

If tan x = sin 45^@. cos 45^@ + sin30^@ , then value of x is - यदि tan x = sin 45^@. cos 45^@ + sin30^@ हो, तो xका मान क्या होगा ?

If xtan45^@sin30^@=cos30^@tan30^@ then the value of x will be a)1 b) 1/2 c) sqrt3 d) 1/sqrt2
