Answer:
Option B

Step-by-step explanation:
we know that
The measure of the interior angle is the semi-sum of the arcs comprising it and its opposite
so
![m\angle PTR=\frac{1}{2}[arc\ PR+arc\ QS]](https://tex.z-dn.net/?f=m%5Cangle%20PTR%3D%5Cfrac%7B1%7D%7B2%7D%5Barc%5C%20PR%2Barc%5C%20QS%5D)
substitute the given values
![m\angle PTR=\frac{1}{2}[140^o+106^o]](https://tex.z-dn.net/?f=m%5Cangle%20PTR%3D%5Cfrac%7B1%7D%7B2%7D%5B140%5Eo%2B106%5Eo%5D)

If the Y value is the only one changing, the slope is undefined, as it is vertical. the answer is undefined.
Answer:
3x+7+ x= -11-2x
4x + 2x = -11-7
6x = -18
x = -18/6
x = -3
therefore , the number is -3
now,
by putting value,
3x+7+x=-11-2x
3*(-3)+7+(-3)=-11-2*(-3)
-9+7-3=-11+6
-5=-5
