Answer:
A) -180
Step-by-step explanation:
The measure of the angle on the attached figure is
There are two ways to measuring it
1. Counterclockwise: In this the sign is positive
So,
We can write
180°,
180°+360° = 540°,
180° + 2(360°) =180°+720° =900°,
2. Clockwise: In this, the sign is negative
So,
We can write
-180°,
-180° - 360° = -540°,
-180° - 2(360°) = -180° - 720° = -900°
Hence, the correct option is A.
