Geometry tells us, then, that the angle of depression and angle of elevation are alternate interior angles, and they will have the same measure. What is the angle of depression explained through a drawn diagram? To draw a diagram for the angle of depression, start at the observer. Draw a...

An angle of elevation is formed between a horizontal plane and a line of sight to something that is up. An angle of depression is formed between a horizontal plane and a line of sight to something that is down. How do you find the angle of elevation and distance? To find the angle ...
EVALUATING METHOD OF TILT ANGLE OF OPENING OF MINUTE DEPRESSION OF SURFACE OF METALLIC PLATEPURPOSE: To enable quantitative evaluation of the shape in the depth direction of a dull groove by preparing a diagram of distribution of tilt angles on the basis of a diagram of three-dimensional ...
Note:Angle of elevation is formed when an object is above the sight of an observer. The upward angle from the point of sight is known as the angle of elevation, whereas the angle of depression is when an object is kept below the line of sight of an observer....
How to find angle of depression without calculator? How do you use a calculator to find x if sin(x) = 3/5? Find the following trigonometric function without using a calculator: cos (30^o). If you use the inverse sine to find the measure of an angle with a given sine, explain ho...

In an anti-submarine exercise, the depression angle measured from our warship A to asubmarine C was 30°, and the depression angle from the anti-submarine helicopter B, whichwas 2000 metres directly above the warship A, to the submarine C was 68°. Using the datagiven, find how many ...
