Angle of elevation: tan-1(100/130) = 37.6 degrees rounded to one decimal place
tan(A) = 120/100 =39.81 degrees
If the angle of elevation is 32 degrees then using the tangent ratio in trigonometry the height of the tree is 18.75 feet rounded up to two decimal places
It is tan-1(170/200) = 40.365 degrees to 3 decimal places
Your best bet here would be to use trigonometry. One stand a given distance away from the tree and sight the top of the tree, say with a clinometer, to measure the angle of elevation. Then knowing the angle and the distance you are from the tree, the height of the tree can be calculated with a tangent function.
To calculate that, you'd need to know the angle of the light source or the time of day or have some other object to compare it to.
The flagpole is 15.92 metres, approx.
If you mean the height of the building then it works out as 466.5063509 feet
Your missing the angle of elevation or depression.
The height of a boy that casts a 4 foot long shadow depends on the angle of the sun. A tangent can be used to calculate his height if we know the angle of the sun using the equation: Height = shadow length x tangent of the angle of the sun. Using a calculator, it is easy to get the value of the tangent for any angle and then complete the equation.
It is: tan(52)*9 = 11.519 meters rounded to three decimal places
18.6 m/52.6 degrees tan= 14.2
It is: 27.35 degrees rounded to two decimal places
It depends on the time of day because the angle of the sun will determine the shadow length
36 degrees
tan(A) = 120/100 =39.81 degrees
Use the tangent ratio: 23*tan(23) = 9.762920773 Answer: 10 meters to the nearest meter
