Find the measure of the angle with a protractor. Describe the steps you follow.

  130°

Step-by-step explanation:

1. Obtain an undistorted picture of the angle. (I enlarged it on my flat computer screen.)

2. Position the protractor so the center mark is on the vertex and the 0° mark is aligned with one ray of the angle.

3. Read the angle measure on the protractor scale, recognizing that the value is more than 90°. (My protractor has two scales, each supplementary to the other.)

It is best to use the original of the angle as printed on the original curriculum materials. Any photocopying or printing can distort the angle, giving it a different value that originally intended. (Dilation does not change the angle, but often copiers and cameras have a different scale factor in one direction than in another. That does change the angle's measure.)
