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

Marat540 [252]

Given:

Four series of angles are given.

To Find:

Identify the series with the correct order from greatest to least.

Solution:

the correct order from greatest to least is what is shown in the fourth option, i.e.,

$330$

Calculation:

Now, we use the fact that

$\pi =180$

to calculate the values of

$\frac{\pi}{2}, \frac{2\pi}{3}, \frac{7\pi}{6}, \frac{5\pi}{3}$

So, we have

$\frac{\pi}{2} = 90\\\\\frac{2\pi} {3}=\frac{(2)(180)}{3} = 120\\\\ \frac{7\pi} {6}=\frac{(7)(180)}{6} = 210\\\\ \frac{5\pi} {3}=\frac{(5)(180)}{3} = 300\\\\$

Looking at the above values, we see that the correct order from greatest to least is what is shown in the fourth option, i.e.,

$330$
