# In Problems $1-3$, convert each angle in degrees to radians. Express your answer as a multiple of $\mathrm{\pi }$.$2.-400°$

The angle in radian measure is $-\frac{20\mathrm{\pi }}{9}$.

See the step by step solution

## Step 1. Given information

Given angle measure in degree is $-400°$.

To convert degree measure to radian, multiply degree measure to $\frac{\mathrm{\pi }}{180°}$.

This gives

$-400°×\frac{\mathrm{\pi }}{180°}=-\frac{20\mathrm{\pi }}{9}$.
