A
Which value is not the measure of an angle that is coterminal with an angle of radian measure \( \frac23\pi \)? (Two angles are coterminal if they are drawn in the standard position and both have their terminal sides in the same location.)
\( -\frac13\pi \)
\( -\frac43\pi \)
\( \frac83\pi \)
\( -\frac{10}3\pi \)

In the past we were taught in a driving school that the steering wheel should be held in the position of „ten to two“. Give the degree measure of the angle between the hour hand and the minute hand which corresponds to this time.
\( 115^{\circ} \)
\( 120^{\circ} \)
\( 90^{\circ} \)
\( 105^{\circ} \)

In a driving school we learn to hold the steering wheel in the position of „a quarter to three“. Determine the degree measure of the angle between the hour hand and the minute hand which corresponds to the mentioned time.
\( 172.5^{\circ} \)
\( 180^{\circ} \)
\( 165^{\circ} \)
\( 157.5^{\circ} \)
