On my clock the hour hand is 5.5 cm, the minute hand 8 cm and the second hand 7 cm, measured from the centre. Calculate the distance between the tips of the

a) hour and minute hands at 10 o'clock

b) minute and second hands 15 seconds before 20 past the hour

c) hour and minute hands at 10:20.​

What are the options

Answercounterclockwise rotation about the origin by 180 degrees followed by reflection about the y-axisexplanationthe given figure has verticesrecall that for counterclockwise rotation about the origin, when we rotate figure pqrs counterclockwise through an angle of 180° about the origin, the coordinates will becomenext, we reflect in the y-axis by negating the x-coordinates of the resulting figure to obtain,therefore the correct answer is c
