Question

If sin 6x= cos 3x then the value of x =

Answer 1

sin6x = sin (90-3x)
6x= 90-3x
9x = 90
x = 19
I hope it helps you

Answer 2

We are given the equation Sin$6$x = cos$3$x and we are required to find the value of x. The solution of x will be $10$.

Let us take the equation given to us.

Sin$6$x = cos $3$x

Let us use the formula: Cosθ = Sin($90-$θ).

Sin $6$x = Sin($90-3$x)

Let us cancel Sin from both sides.

$6$x = $90-3$x

$9$x = $90$

x =$10$

Therefore, we can show from the above calculation that x = $10$
