Write the measure of smaller angle formed by the hour and the minute hands of a clock at 7 O’ clock. Also, write the measure of the other angle and also state what types of angles these are.
Measure of the required angle = 30° + 30° + 30° + 30° + 30° = 150°
Measure of the other angle = 360° – 150° = 210°
Angle of measure 150° is an obtuse angle and that of 210° is a reflex angle.
