I dont think that this question is possible.

[tex] \huge \boxed{Answer : - }[/tex]

  • [tex] \sin(3x) = \cos(x + 6) [/tex]

  • [tex] \cos(90 - 3x) = \cos(x + 6) [/tex]

[ Due to complementary relation between sin and cos. ]

  • [tex]90 - 3x = x + 6[/tex]

  • [tex]x + 3x = 90 - 6[/tex]

  • [tex]4x = 84[/tex]

  • [tex]x = 21[/tex]

The value of x = 21
