To be honest the answer is going to be the same.

Well because first of all their is a X in one number instead of the other. Second of all we don't know how much the X equals. And ya that's all.

If the equation equals 0, then it would be x = 7/4. Add the 7/5 to the other side of the equal sign and multiply by the reciprocal of 4/5, which is 5/4, on both sides to cancel it out on the x side.

Please help me on this
Diano4ka-milaya [45]

Answer: Option A.

Step-by-step explanation:

The angle ∠QST and the angle ∠QSR are supplementary.

If two angles are supplementary, means that the sum of both angles is 180 degrees.

Thenrefore

QST+QSR=180\°

Solve for the angle ∠QSR and substitute the value of the angle ∠QST  to find the value of the angle ∠QSR. Then, solving the equation, you get:

QSR=180\°-QST\\QSR=180\°-150\°\\\\QSR=30\°

Then tan(QSR) is:

tan(30\°)=\frac{\sqrt{3}}{3}

This matches with the option A.
