QuestionFind the measure of a positive angle coterminal with $-540^{\circ}$. $\square$

Studdy Solution
Verify that the angle $180^\circ$ is within the standard range of $0^\circ$ to $360^\circ$. Since it is, this is the positive coterminal angle.
The measure of a positive angle coterminal with $-540^\circ$ is:
$$\boxed{180^\circ}$$
