# How do you find an angle with a positive measure and an angle with a negative measure that are coterminal with -80^circ?

Jun 14, 2018

${280}^{\circ} , - {440}^{\circ}$

#### Explanation:

Given: $- {80}^{\circ}$

To be a coterminal angle, you only need to add or subtract multiples of ${360}^{\circ}$:

$- {80}^{\circ} + {360}^{\circ} = {280}^{\circ}$

$- {80}^{\circ} - {360}^{\circ} = - {440}^{\circ}$
