Question

How do you convert $-50$ degrees to radians?

Answer 1

Find the value of radian:

It is known that $2\pi$ radians are equal to ${360}^0$.
The required angle can be calculated as:

$\begin{array}{rcl}-50°\times \frac{\mathrm{\pi }}{180°}\mathrm{radians}& =& -\frac{50°x\mathrm{\pi }}{180°}\mathrm{radians}\\ & =& \frac{-5\mathrm{\pi }}{18}\mathrm{radians}\end{array}$
Therefore, the radian value is $-\frac{5\pi }{18}$radians.
