Question

if sin(3x)= cos(x+6), what is value of x

Answer 1

I dont think that this question is possible.

Answer 2

$\huge \boxed{Answer : - }$

• $\sin(3x) = \cos(x + 6)$

• $\cos(90 - 3x) = \cos(x + 6)$

[ Due to complementary relation between sin and cos. ]

• $90 - 3x = x + 6$

• $x + 3x = 90 - 6$

• $4x = 84$

• $x = 21$

The value of x = 21
