Chapter 13, Problem 6PT

To determine

To calculate:Degree mesures in radian..

Answer to Problem 6PT

The angle measure in radian is $-0.972\pi$ or $-3.053$

Explanation of Solution

Given information:An angle measure is given as $-175°$ .

Formula used:We know that $1°=\left(\frac{\pi }{180°}\right)rad$ .

Calculation: Plug the given angle in the formula, we get

  $1°=\left(\frac{\pi }{180°}\right)rad$

  $\begin{array}{l}-175°=-175°\left(\frac{\pi }{180°}\right)\\ =-0.972\pi \\ =-0.972\times 3.141\\ =-3.053rad\end{array}$
