1. To a man standing outside his house, the angles of elevation of the top and bottom of a window are 60^{\circ} and 45^{\circ} respectively. If the height of the man is 180 \ cm and if he is 5 \ m away from the wall, what is the height of the window? (\sqrt{3} = 1.732)
 
Answer:
 
The height of the window =  
 
(Note: Enter the number in the first box and the unit (short form) in the second box.)
 
2. A statue 1.6 \ m tall stands on the top of a pedestal. From a point on the ground, the angle of elevation of the top of the statue is 60^{\circ} and from the same point the angle of elevation of the top of the pedestal is 40^{\circ}. Find the height of the pedestal. (tan \ 40^{\circ} = 0.8391, \sqrt{3} = 1.732)
 
Answer:
 
The height of the pedestal =  
 
(Note: Enter the number in the first box and the unit (short form) in the second box.)
 
3. The top of a 15 \ m high tower makes an angle of elevation of 60^{\circ} with the bottom of an electronic pole and angle of elevation of 30^{\circ} with the top of the pole. What is the height of the electric pole?
 
Answer:
 
The height of the electric pole =  
 
(Note: Enter the number in the first box and the unit (short form) in the second box.)
