## Q- From a point on the same plane along the horizontal line passes through the foot of a chimney, the angle of elevation of the top of the chimney is 30 ° and the angle of elevation of the top of the chimney is 60 ° at a point on the same straight line proceeding 50 meters to the chimney. Let u write by calculating the height of the chimney.

## Q- Mohit, standing in the midst of a field, observes a flying bird in his north at an angle of elevation of 30 ° and after 2 minutes he observes the bird in his south at an angle of elevation of 60 °. If the bird flies in a straight line all along at a height of 50 √ 3 meters, let us find it speed in kilometer per hour.

## Q- A bridge is situated at right angle to the bank of the river. if one moves away a certain distance from the bridge along this side of the river, the other end of the bridge is seen at an angle of 45 ° and if someone moves a further distance of 400 meters in the same direction, the other end is seen at an angle of 30 °. Let us find the length of the bridge.
