Using trigonometry the angle of elevation is 77 degrees rounded to the nearest degree
By means of trigonometry if you know the angle of elevation or by comparing it with a nearby object if you know its height and shadow length.
Use the tangent angle of elevation which works out as 31.7497 degrees to four decimal places
the angle at which a shadow is formed
14 feet
If you also know its shadow then you can work out the angle of elevation
Light leaves the lamp and travels in straight lines from its point source. As you move away from the source, the angle between you and the light changes and this the length and position of your shadow changes.
Using trigonometery if you know the length of its shadow and angle of elevation
WARNING: Do not, under any conditions, look at the sun, directly or indirectly.The find the elevation of the sun, measure the angle that an object's shadow from the sun makes. One way to do this is with a stick in the ground. Assuming the stick is perpendicular to the ground, the ratio of the stick's length to the shadow's length is the tangent of the angle of elevation. Solve for inverse tangent, and you have the angle.
That depends on the angle of elevation which has not been given.
You can use trigonometry to find the angle of elevation. Let x be the distance from the tip of the shadow to the base of the pole and the height of the pole be y. Then, tan(60 degrees) = y/x. Given that the height of the pole is 12 feet, you can solve for x to find the angle of elevation.
Your missing the angle of elevation or depression.
Using trigonometry the angle of elevation is 77 degrees rounded to the nearest degree
Angle of elevation: tan-1(100/130) = 37.6 degrees rounded to one decimal place
It is: 27.35 degrees rounded to two decimal places
By means of trigonometry if you know the angle of elevation or by comparing it with a nearby object if you know its height and shadow length.
