Answer: x = 45 degrees
Explanation:
We can see that there is a straight line. A straight line is 180 degrees.
We also see a 90-degree angle. There are 2 angles that equal the same amount.
This gives the equation below:
90 + 2x = 180.
Now, we subtract 90 from both sides.
2x = 90.
Now, we divide both sides by 2.
x = 45.
This means that our final answer is 45 degrees.
