## 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.
