• 21.6Angles of elevation and depression. If, in Figure 21.27, BC represents horizontal ground and AB a vertical flagpole, the angle of elevation of the top of the flagpole, A, from the point C is the angle that the imaginary straight line AC must be raised (or elevated) from the horizontal CB; i.e., angle θ .•The angle of elevation of an object as seen by an observer is the angle between the horizontal and the line from the object to the observer's eye (the line of sight). The angle of elevation of the object from the observer is °. If the object is below the level of the observer, then the angle between the horizontal and the observer's line of sight is called the angle of depression. •Nov 28, 2020 · The angle of elevation is the angle formed by the ground and a line extending from the object upwards to the observer. As long as the ground and the line extending from the observer to the horizon are parallel, the angles of depression and elevation between the observer and the object are always equal.

    The opposite side is given to us: 2, but the hypotenuse is not. Since we have a right-angled triangle, we can use Pythagoras to find the hypotenuse. If the hypotenuse is c, then a and b are both 2, so the equation a^2+b^2=c^2 becomes: c^2=2^2+2^2=4+4=8 . Square rooting both sides, we get: c=\sqrt{8}=2\sqrt{2}
