## Question:

Tony is standing at sea level. From his location, the angle of elevation of the top of Blue Mountain is {eq}23^{\circ} {/eq}. Staying at sea level, he walks 200 yards toward the mountain. The angle of elevation of the top is now {eq}27^{\circ} {/eq}.

Find the height of Blue Mountain.

## Angle Of Elevation:

Angle of Elevation is defined as the angle formed between the line of sight of the observer and the horizontal. For example when an observer sees an object which is a height from ground level then the angle which the observer's eye makes with the horizontal is known as angle of elevation.
