Calculating angles
From the question, we are to determine the measure of the angle shown
For the given protractor,
The measure between any two lines is 10°.
Also, there are 10 tick marks between any two lines.
∴ 15 tick marks will have a measure of 15°
Then,
The measure of a protractor showing an angle going through the fifteenth tick mark after two hundred sixty five degrees will be
265° + 15° = 280°
Hence, the measure of the angle shown is 280°
