WebStart the solution by writing the formula for coterminal angles. Let ∠θ = ∠ɑ = ∠β = ∠ɣ. Solve for the angle measure of x° for each of the given angles in standard position. The resulting solution, ∠ɑ, is a Quadrant III angle while the ∠β is a Quadrant II angle. ∠θ = x° + 360°n. ∠ɑ = x° + 360° (1) 550° = x° + 360°.
