82.42 + 1.8 = 84.22
Yup
aisha said:Jennie stands 30 m from the base of a high rise building. The angle of elevation from her eyes to the top of the tower is 70°. How high is the tower if her eyes are 1.8 m above the ground?
Is the answer to this 82.42 m + 1.8m=84.22 m?
If you check my post above I said that my eye level was about 1.95m (probably more now :tongue2:) and I am not a giant. Just rather tall.qweretyq said:1.9 meters is not a giant...
its about 6 feet 3 inches...
im 6' exactly
I most likely would but you find a female 2.15m :tongue2:dextercioby said:Since I'm only 1.71,i feel quite uncomfortable when a lady next to me is towering 20 cm more...Bob,if u were near a girl at 2.15,u'd feel the same way... :tongue2:
A little harsh really.iodmys said:I'd say that she's "deformed."
To calculate the height of a high rise building using trigonometry, we need to use the tangent function. First, we need to measure the angle of elevation from the ground to the top of the building. Then, we can use the tangent function (opposite/adjacent) to find the height of the building.
To calculate the height of a high rise building using trigonometry, we need to measure the angle of elevation from the ground to the top of the building and the distance from the base of the building to where the angle is being measured. These two measurements are necessary to use the tangent function to find the height of the building.
Yes, trigonometry can be used to calculate the height of any high rise building as long as we have the necessary measurements. However, it is important to note that there may be some limitations, such as extreme weather conditions or obstacles blocking the view of the top of the building, which may affect the accuracy of the calculation.
One common mistake to avoid is using the wrong angle or distance measurements. It is important to make sure that the angle of elevation is measured from the ground to the top of the building, and the distance is measured from the base of the building to where the angle is being measured. Another mistake to avoid is using the wrong trigonometric function. In this case, we need to use the tangent function, not sine or cosine.
Yes, there are other methods for calculating the height of a high rise building, such as using a measuring tape, laser rangefinder, or even drones. However, trigonometry is often preferred as it can be used from a safe distance and does not require any physical measurements on the building itself.
