The angle of elevation is looking at an object above your line of sight.
It is the alternate angle to the angle of elevation
If the base of the elevation is at a distance d from the observer, then the highest point is at a height = d*tan(angle of elevation)
The front elevation is in the centre in both projections. In 1st angle projection the end elevation is on the opposite side of the front elevation and the plan view is below the front elevation. In 3rd angle projection the plan view is above the front elevation and the end elevations are on the same side as viewed
The angle of elevation is increased as the plane flies closer because of the decreasing distance.
h[cot(38.5)-cot(40)]=21.2 solve for h you get h=324mters
The angle between the sun's position in the sky and the horizon is called the altitude of the sun. It is the measurement from the horizon to the center of the sun's disk. This angle changes throughout the day as the sun moves across the sky.
the position of the moon in relativity to the sun and earth....the angle casts a shadow across the moon
Angle of elevation is looking upwards to an object and angle of depression is looking downwards to an object
A sextant measures the angle of elevation between the horizon and the north star. Along with charts, it can be used to calculate your position on the sea fairly accurately.

Angle of elevation: tangent angle = opposite/adjacent and by rearranging the given formula will help to solve the problem
