It is: tan(52)*9 = 11.519 meters rounded to three decimal places
When the angle of elevation equals 45 degrees. tan-1(1) = 45 degrees.
It is: 27.35 degrees rounded to two decimal places
Use the tangent ratio: 23*tan(23) = 9.762920773 Answer: 10 meters to the nearest meter
Using the tangent ratio height of telegraph pole is 55 feet to the nearest integer.
Height of telephone pole: 20*tan(70) = 55 feet rounded
When the angle of elevation equals 45 degrees. tan-1(1) = 45 degrees.
It is: 27.35 degrees rounded to two decimal places
(Height of the building)/(length of the shadow) = tangent of 31° .Height = 73 tan(31°) = 43.9 feet (rounded)
The flagpole is 15.92 metres, approx.
Required angle has a tangent of 7.6/6.1 ie 1.249. This is 51.25 degrees.
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.
Angle of elevation: tan-1(100/130) = 37.6 degrees rounded to one decimal place
18.6 m/52.6 degrees tan= 14.2
If you also know its shadow then you can work out the angle of elevation
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 ratio: 23*tan(23) = 9.762920773 Answer: 10 meters to the nearest meter
Using trigonometery if you know the length of its shadow and angle of elevation
