Answer:
133 degrees
Step-by-step explanation:
The angle 47 degrees is on a straight line, and the angles on a straight line add up to 180 degrees.
So, to find the angle parallel to 47 degrees, subtract 47 degrees from 180 degrees
180 - 47 = 133 degrees
Now, the relationship between the angle that is 133 degrees and the angle of x is that they are corresponding angles.
And corresponding anglea are the same.
Thereforw, x = 133 degrees
