how to find angle of depression with 2 sides?
4167
The angle of depression may be found by using this formula: tan y = opposite/adjacent. The opposite side in this case is usually the height of the observer or height in terms of location, for example, the height of a plane in the air. The adjacent is usually the horizontal distance between the object and the observer.

In the ambiguous case we first find the height by using the formula h=bsinA . Note that A is the given angle and its side is always a so the other side will be b . h<a<b then then there are two solutions or two triangles. h<b<a then there is one solution or one triangle.

If you are looking at an object above the horizon then the angle between the horizontal and your line of sight is the angle of elevation. If you are looking at an object below the horizon then the angle between the horizontal and your line of sight is the angle of depression.

Using the sine and cosine rules to find a side or angle in a triangle. The sine rule can be used to find an angle from 3 sides and an angle, or a side from 3 angles and a side. The cosine rule can find a side from 2 sides and the included angle, or an angle from 3 sides.

If a person stands and looks down at an object, the angle of depression is the angle between the horizontal line of sight and the object. Trigonometry can be used to solve problems that use an angle of elevation or depression.

Angles of Elevation and Depression. You can use right triangles to find distances, if you know an angle of elevation or an angle of depression. ... For example, if you were standing on top of a hill or a building, looking down at an object, you could measure the angle of depression.

The angle of elevation is the angle formed between the horizontal and our line of sight when we look up. The angle of depression equals the angle of elevation because they from alternate interior angles or congruent angles located on different parallel lines cut by a transversal line.

To find the complement of an angle x, subtract x's measurement from 90 degrees: 90 degrees - x degrees = the measure of x's complementary angle. To find the supplement of an angle y, subtract y's measurement from 180 degrees: 180 degrees - y degrees = the measure of y's supplementary angle.
