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.
\( 172.5^{\circ} \)
\( 180^{\circ} \)
\( 165^{\circ} \)
\( 157.5^{\circ} \)

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.
\( 115^{\circ} \)
\( 120^{\circ} \)
\( 90^{\circ} \)
\( 105^{\circ} \)

The radian measure of the angle \( \theta \) is \( \frac{\pi}2 \). What is the sum of all the radian measures of the angles coterminal to \( \theta \) from the interval \( [-5\pi; 5\pi] \)? (Two angles are coterminal if they are drawn in the standard position and both have their terminal sides in the same location.)
\( \frac52\pi \)
\( 0 \)
\( 3\pi \)
\( \pi \)

The radian measure of the angle \( \theta \) is \( \frac{\pi}3 \). How many values from the set \( M = \left\{\frac43\pi; \frac73\pi; \frac83\pi; \frac{13}3\pi; -\frac53\pi; \frac{61}3\pi; -\frac{61}3\pi \right\} \) are the measures of angles coterminal to \( \theta \)? (Two angles are coterminal if they are drawn in the standard position and both have their terminal sides in the same location.)
