Albie is sitting in a classroom and sees a picture on the black board at a height of 1.5 m from the horizontal level of sight. The angle of elevation of the picture is 30 degrees. As the picture is not clear to her, she moves straight towards the black board and sees the picture at an angle of elevation of 45 degrees. Find the distance moved by Albie.

An air traffic controller needs to calculate the height of an incoming jet. The jet's angle of elevation is 28 degrees. The jet is 140 kilometers (horizontal distance) from the landing strip. Calculate the height of the jet.

Jack and Jill were on the same side of a hill but were 34 m apart. Both were lying on the ground looking up at the peak of a hill. Jill, who is closer to the hill, determined that the angle of elevation to the top was 37 degree. Jack determined that the angle of the elevation to the top from his position was 22 degree. How high is the peak of the hill

An American-Italian high school hockey player from the North Shore is standing 10 feet from a building. If the vertical distance from the ground to his dark eyes is 5 feet and if the angle between a horizontal line and his line of sight to the top of the building is 80°, find the height of the building.

An airplane is one mile above sea level when it begins to rise at a constant angle of 2 ° for the next 70 miles, measured above the surface. How far away will the plane be when it reaches the 70-mile point?

To estimate the height of a building, two students find the angle of elevation from a point (at ground level) down the street from the building to the top of the building is 38°. From a point that is 250 feet closer to the building, the angle of elevation (at ground level) to the top of the building is 49°. If we assume that the street is level, use this information to estimate the height of the building. The height of the building is feet.
