To solve for x when Cos(3x) = Sin(7x), we will use the trigonometric identity Cos(x) = Sin(90° - x).
Starting with Cos(3x) = Sin(7x), we can substitute Cos(3x) with Sin(90° - 3x) using the identity:
Sin(90° - 3x) = Sin(7x)=> 90° - 3x = 7x (since Sin(x) = Sin(180° - x))=> 90° = 10x=> x = 9°
Therefore, the solution for x is 9 degrees.
