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.

In stadia leveling, the difference in elevation V is computed from the stadia intercept and vertical angle. If the value of stadia constant is 100(assumed errorless) and the errors in the stadia intercept and vertical angle are 0.003 and 45 seconds of arc respectively, evaluate the error in V for stadia intercept=1.200 and vertical angle=15 degrees. 1 kssin20 + csine

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:
