Coterminal angles are angles that are made by the positive x-axis of the coordinate plane. The positive angle that is less than 2π and is coterminal with 14π/6 is 1/3π.
<h3>What are coterminal angles?</h3>
Coterminal angles are angles that are made by the positive x-axis of the coordinate plane.
The angle that 14π/6 makes from the positive x-axis is 1/3π, which is equal to 60°.
Hence, the positive angle that is less than 2π and is coterminal with 14π/6 is 1/3π.
