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.
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
Use the tangent ratio: 23*tan(23) = 9.762920773 Answer: 10 meters to the nearest meter
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.
Using trigonometery if you know the length of its shadow and angle of elevation
Using the tangent ratio height of telegraph pole is 55 feet to the nearest integer.
