A hot air balloon is released to the air and fly vertically upwards, with the assumptionthat no wind is blowing at the balloon. After a while, observer A and observer B,who are 2 km apart from each other, managed to see the balloon with the elevationangle of 40° and 70° respectively from the same level of horizontal line. With the aidof diagram, calculate distance of balloon from ground, assuming the balloon is abovethe horizontal line of the two observers.

9. Bertha works in a 32-story building (building-A) that is 140 meters tall located on a boulevard with a slope of 5°. Several blocks uphill, there is another tall office building (building-B), and Bertha decides to compare the height of both building. From the street level at the entrance of her building (building-A) she measures the angle of elevation to the top of the second building (building-B) and finds 20°. She climbs to the roof of her building and measures the second angle of elevation of 12°. Which building is taller and by how much? Round your answer to the nearest meter. EXPRESS YOUR ANSWER AS: "building-X; xxx meters" *

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?
You are at the top of a mountain and in the distance, you can see a crashed alien ship. You want to go investigate but want to know the distance from the top of the mountain to the alien ship! You’re able to measure that the angle between your horizontal line of sight and the alien ship is 41◦. You know that the mountain you’re on top of has a height of 275m. Find the length of the line of sight from the alien ship to you if you shine a line diagonally to the alien ship.

9. A surveyor is mapping a large marsh in a state park. He walks and measures a straight line south from a cliff for 0.75 mile to a large tree. He walks east, but he has to make a detour around the marsh. He gets around the marsh to a spot where he is perpendicular to the large tree and the trail he originally walked south on. He looks northwest and measures a 40° angle (ZA) northwest to the cliff from his line of sight to the large tree. He measures the distance back to the starting point at the cliff as 1.17 miles. What is the straight-line distance from the large tree east to ZA? What is the tangent of ZB , the angle at the cliff? Clff 0.75 mile 1.17 mile 40 Tree
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:
