# How do you find an angle with a positive measure and an angle with a negative measure that are coterminal with -400^circ?

$- {40}^{\circ}$
${320}^{\circ}$
Angle with negative measure --> $- 400 = - \left(40 - 360\right) = - {40}^{\circ}$
Angle with positive measure --> $\left(360 - 40\right) = {320}^{\circ}$
