**From degrees to radians**

**Find the radian measure of the angle $-{45}^{\circ}$. Round your answer to three decimal places**.

Angle in radians is $\mathbf{-}\mathbf{0}\mathbf{.785}$

An angle of $-{45}^{\circ}$ and we have to convert it in radians.

We already know how to convert an angle to radians by multiplying it by $\frac{\pi}{180}$.

The answer will be in radians.

Here is the calculation-

${1}^{\circ}=\frac{\pi}{180}\phantom{\rule{0ex}{0ex}}-{45}^{\circ}=\frac{\pi}{180}\times (-45)\Rightarrow -0.785$
