Since TSQ and QSR are supplementary, they give 180 when summed. TSQ is 150, so QSR must be 30.

Therefore, you have

$\tan(30)=\dfrac{\sin(30)}{\cos(30)}=\dfrac{\frac{1}{2}}{\frac{\sqrt{3}}{2}} = \dfrac{1}{2}\cdot\dfrac{2}{\sqrt{3}}=\dfrac{1}{\sqrt{3}}=\dfrac{\sqrt{3}}{3}$

So, x > 7 - 2; x >5 or

4 - x > 6; 4 - x - 6 > 0;

4 - 6 -x > 0;

- 2 -x > 0;

-2 > x;

Finally, x > 5 or x < -2;
