Using the equation, you get 12b+38=150
12b=112
B is 28/3. Your answer is correct. You round up because if you round down, then you won't have enough.
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)
