Find the height of the house. 10 The feet of two vertical poles of height 3 m and 7 m are in line with a point P on the ground, the smaller pole being between the taller pole and point P at a distance 20 m from point P. The angle of elevation of the top (T) of the taller pole from the top (R) of the smaller pole is 30°. Calculate: a) the distance RT. b) the distance of the foot of the taller

Q3. The angle of elevation of the top of a chimney from the top of a tower is 60° and the angle of depression of the foot of the chimney from the top of the tower is 45°. If the height of the tower is 75 m, find the height of the chimney. According to pollution control norms, the minimum height of a smoke emitting chimney should be 100 m. State if the height of the above mentioned chimney meets the pollution norms. What value is discussed in this question?
10. Two kids, Albert and Bhara, are 20.0 m apart. Albert sees a soccer ball 25.0 m away. If the angle between the line formed by Albert and Bhara and the line from Albert to the soccer ball is 25°, how far is Bhara from the soccer ball? Correctly round your answer to the nearest tenth of a meter.

4. A young man launches a drone from the ground 60ft from where he is standing. As the drone hovers above the ground, the gps on the controller reads that the distance from the young man to the drone is 90 ft with an angle of elevation of 48 degrees. If the drone continues to fly away from the man maintaining the same vertical height. Sketch a diagram of the situation and determine the distance between the young man and the drone when the angle of elevation is now 40 degrees. Extra Credit:

Q7. A cellphone transmitter is placed at the top of a vertical tower. Cables are used to help support the tower. One end of a cable is anchored to the ground, and the other end is attached to the top of the tower. The two supporting cables are anchored to the ground at points A and B, which are 12 m apart. The angle between the ground and the cable anchored to points A and B is 62° and 72° respectively. Determine the height of the tower. Round your final answer to the nearest meter.
