Use a protractor to measure the angle x as shown in the picture below. Print out this page if you need to.
First, we place the protractor on the vertex of the angle as shown below:
Now, we rotate the protractor about the vertex of the angle so that the base line is along the line or arm as shown below:
By reading the inner scale, we can see that the angle is 65°.
Angle x is 65°. Clearly, the answer is B.
