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

Answer:-[tex]\frac{3\pi}{10},60^{\circ},\frac{\pi}{2},\frac{2\pi}{3},255^{\circ}[/tex]
Explanation:-
Substitute [tex]\pi=180^{\circ}[/tex] , we get
1. Correct.
[tex]\frac{3\pi}{10},60^{\circ},\frac{\pi}{2},\frac{2\pi}{3},255^{\circ}[/tex]
=54°,60°,90°,120°,255°
2. Not correct.
255° is not less than 60.°
3. Not correct.
[tex]\frac{\pi}{2}[/tex]=90° which is not less than 60°.
4. Not correct
255° is not less than 60°.
