Answer:

-120 degrees.

Step-by-step explanation:

This triangle has a rotational symmetry of 3 (it repeats its orientation 3 times as it makes a complete circle around the center), so the angle of rotation is 360 / 3 = 120 degrees.

As the rotation is counter clockwise strictly speaking the answer is -120 degrees.
