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
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:
Then 
is:
This matches with the option A.

Answer:
Supplementary angles add to 180 degrees.
Angles of a triangle add to 180 degrees.
So, the angles of this triangle are 2x, 3x, and 70.
This means we can have the equation: 5x+70=180, and 5x=110, meaning that x=22
