Answer:
Six angle which has the value -0.5 will be
-390 , -750, -1110, -1470, -1830, -2190
Explanation:
We have given that

So

Now we have to find the possible negative value of
which has same value as -0.5
We know that after 360° angle will repeat itself
So angle will be -30 - 36 = -390
-390-360 = -750
-750-360 = -1110
-1110-360 = -1470
-1470-360= -1830
-1830-360 = - 2190
