what is the value of x? 20,35,60or70

Answer:
x=20
Step-by-step explanation:
∠TRS and ∠VRW are vertical angles, so the measure of the angles will be the same.
First, set the two values equal to each other: x+40=3x
Then, subtract x from both sides to isolate x: 40=2x
Finally, divide both sides by 2 to find the value of x which is 20
