Question

write the measure of the smaller angle formed by the hour and the minute hand of a clock at 7 o'clock also write the measure of the Other angle and also state what type of angle these are

Answer 1

Given : angle formed by the hour and the minute hand of a clock at 7 o'clock

To Find : smaller angle  and other angle

Step-by-step explanation:

At 7 O clock

Minute Hand is at 12

Hour Hand  is at 7  

Hour Hand rotates 360° in 12 Hours

hence 30° in 1 hour

=> 210°  in 7 Hours

Minute Hand is at  0 °

Angle Between Hour and minute Hand = 210°  reflex angle  

210 > 180  

Hence smaller  angle = 360° - 210° = 150°   Obtuse angle

Smaller angle  150°   Obtuse angle

other angle    210°  reflex angle
