Which of the following are in correct order from greatest to least?

Option 4. is the correct option.

Step-by-step explanation:

The given angles are π/2, 330°,5π/3, 7π/6, 2π/3.

we have to arrange these angle in decreasing order.

First we will convert these angles from radian to degree.

π/2 = 90°

5π/3 = 5×180/3 = 300°

7π/6 = 7×180/6 = 210°

2π/3 = 2×180/3 = 120°

and 330°

Now the decreasing order of the angles is

330°, 300°, 210°, 120°, 90°

Therefore 330°, 5π/3, 7π/6, 2π/3, π/2 is the correct answer.
