Final answer:
To find the measure of an angle with protractor readings of 107 and 43 degrees, subtract the smaller reading from the larger one, yielding 64 degrees as the measure of the angle.
Step-by-step explanation:
The question asks to find the measure of an angle where the protractor readings for two rays are 107 and 43 degrees. To find the measure of the angle, you subtract the smaller protractor reading from the larger one. Therefore, the measure of the angle is:
107 degrees - 43 degrees = 64 degrees.
The correct answer is: A) 64 degrees.
