#### Answers

- (a)
- (c)
- (c)
- (a) Angle covered by hour hand in 12 hours = 360 degrees

Angle covered by hour hand in 3 hours 15 minutes i.e. 13/4 hours = [(360/12 * (13/4)]

= (195/2)^{o}

- (b)

(360/12) * 7 = 210^{o}

- (b)

Angle traced by hour hand at 10 pm = (360/12) * 10 = 300^{o}

Angle traced by minute hand in 15 min = (360/60) * 15 = 90^{o}

Required angle = 210^{o}

- (b)

Angle traced by hour hand at 2:30 pm = (360/12) * (5/2) = 75^{o}

Angle traced by minute hand in 30 min = (360/60) * 30 = 180^{o}

Required angle = 105 degrees

- (a)
- (b)

(360/12)* 6 = 180^{o}

- (d)

Angle traced by hour hand at 7 pm = (360/12) * 7 = 210^{o}

Angle traced by minute hand in 20 min = (360/60) * 20 = 120^{o}

Required angle = 90^{o}
