Question

find all angles that are coterminal with the given angle. 240°
° for all integers k.

Explanation:

Step1: Recall coterminal - angle formula

Coterminal angles of an angle $\theta$ are given by $\theta + 360^{\circ}k$, where $k$ is an integer.

Step2: Substitute the given angle

Given $\theta = 240^{\circ}$, the coterminal angles are $240^{\circ}+360^{\circ}k$, for all integers $k$.

Answer:

$240 + 360k$
