Chapter 13.5, Problem 2ST

a.

To determine

The given value of radians into degree.

Explanation of Solution

Given information:

The given radian is $\frac{-5\pi }{6}$

Calculations:

The given radians is $\frac{-5\pi }{6}$

Now to convert the radians into degree we have to multiply with $180°$ and divide with $\pi$ .

  $\frac{-5\pi }{6}=\frac{-5\pi }{6}\times \frac{180}{\pi }=-150°$

b.

To determine

The given value of radians into degree.

Explanation of Solution

Given information:

The given radians is 2.5

Calculations:

The given radians is $2.5$

Now to convert the radians into degree we have to multiply with $180°$ .

  $2.5=2.5\times 180=450°$
