how know
To measure the angle with a protractor, follow these steps:
1. Place the protractor on the angle so that the center of the protractor lines up with the angle's vertex.
2. Make sure the zero degree line on the protractor is aligned with one of the angle's sides (one ray).
3. Look at the scale on the protractor and determine where the other side (the second ray) of the angle intersects the scale.
4. The degree measure at this intersection point is the measurement of the angle.
In this case, if you use a protractor and follow the steps, you will find that the angle measures 60°. Therefore, the answer is D) 60°.
