Answer:
C.
Step-by-step explanation:
We have been given a figure of angles formed on a straight line.
Since we know that the angles on a straight line add up-to 180 degrees. Upon using this property we can set an equation as:
![31^o+x^o+40^o=180^o](https://tex.z-dn.net/?f=31%5Eo%2Bx%5Eo%2B40%5Eo%3D180%5Eo)
Let us subtract 40 and 31 degrees from both sides of our equation to solve to x.
![x=180^o-31^o-40^o](https://tex.z-dn.net/?f=x%3D180%5Eo-31%5Eo-40%5Eo)
Upon factoring negative sign from right side of our equation we will get,
![x=180^o-(31^o+40^o)](https://tex.z-dn.net/?f=x%3D180%5Eo-%2831%5Eo%2B40%5Eo%29)
Therefore, the equation
can be used to find the value of x and option C is the correct choice.
The answer is b. 72 square units.
