The problem asks for the value of x in degrees, given the equation:
$ \sqrt{2} \sin(5x - 5)^\circ = \tan 45^\circ $
Evaluate Known Tangent Value: We know that $\tan 45^\circ = 1$. Substituting this into the equation gives:
$ \sqrt{2} \sin(5x - 5)^\circ = 1 $
Isolate the Sine Function: Divide both sides by $\sqrt{2}$:
$ \sin(5x - 5)^\circ = \frac{1}{\sqrt{2}} $
Identify the Angle for Sine: Recall that $\sin 45^\circ = \frac{1}{\sqrt{2}}$. Therefore, we can equate the angles:
$ (5x - 5)^\circ = 45^\circ $
Solve for 5x: Add 5 to both sides of the equation:
$ 5x^\circ = 45^\circ + 5^\circ $
$ 5x^\circ = 50^\circ $
Solve for x: Divide both sides by 5:
$ x = \frac{50^\circ}{5} $
$ x = 10 $
The value of x is 10 degrees.
