Solve for x

sin(x-20) = cos(x)

Step-by-step explanation:

We can use the identity: to simplify this into:

The identity sin(x) = sin(y)  -->  , can be used to simplify this further:

   (Add 20 to both sides)

   (Add x to both sides)

   (Divide both sides by 2)

   (Simplify)

   If required, we can convert this into radians:
