Problem

An angle is given as −7π3-\dfrac{7\pi}{3} radians, measured clockwise from the initial side. (i) Express this angle in degrees. (ii) Determine its equivalent positive angle in degrees that lies between 0∘0^{\circ} and 360∘360^{\circ}. (iii) Convert the angle found in part (ii) back to radian measure, expressing your answer with π\pi. (iv) State the quadrant in which the terminal side of the original angle −7π3-\dfrac{7\pi}{3} lies.
