for example 2: the minute hand has to cover 120° more to form a right angle coz it has already covered 30° to form the first right angle. so it should be (6*30°)=120° isn't it? plz help ma'am I got confused
In part 5, how the minute hand will cover only 210°, in the movement of minute hand the hour hand will also move some distance, so for the formation of right angle the minute hand should be somewhat in between 7 and 8, so the distance covered by the minute hand must be in between 210° and 240°. So why you took 210° to solve the problem .
