Answer:

about 1.4288993 radians

Explanation:

The angle to terminal arm A is ...

∠A = arctan((-4/5)/(-3/5)) ≈ 4.0688879 radians

The angle to terminal arm B is ...

∠B = arctan((-1/√2)/(1/√2)) ≈ 5.4977871 radians

Then the angle between the arms is ...

5.4977871 -4.0688879 ≈ 1.4288993 . . . radians
