how to find the height of a building using trigonometry

For example, architects can use the tangent function to compute a building's height if they know their distance from the structure and the angle between their eyes and the building's top; clinometers can help you measure those angles. If the angle of elevation from the top of the shorter building to the top of the taller building is 10°, what is the difference in the height of the two buildings? So, the height of the balloon from the ground is 173.2 m.You can also visit the following web pages on different stuff in math. Another group went with the more traditional approach of creating a clinometer to measure the building’s angle of elevation from a certain distance, and then using that angle to measure its height. Here, AB represents height of the building, BC represents distance of the building from the point of observation.In the right triangle ABC, the side which is opposite to the angle 60 degree is known as opposite side (AB), the side which is opposite to 90 degree is called hypotenuse side (AC) and the remaining side is called adjacent side (BC). How far is the boat from the base of the cliff? Give your answer to an appropriate degree of accuracy.Assume the man’s eye-level is (approximately) 1.7 m above the ground.That is far too precise (being to the nearest 10 cm). Here, AB represents height of the building, BC represents distance of the building from the point of observation. Find the  height of the balloon from the ground. Now, we need to find the distance between foot of the ladder and the wall. is the angle between the horizontal line of sight and the object.If a person stands and looks down at an object, the is the angle between the horizontal line of sight and the object.Trigonometry can be used to solve problems that use an angle of elevation or depression.He stands 50 m away from the base of a building. State any assumptions you have made in your calculation.115.2 m is far too precise (being to the nearest 10 cm). An estimate to an appropriate degree of accuracy would be 140 m. (Note this is also about the same degree of accuracy as the 50 m and 70° that are used in the question).From the top of a 72 m high vertical cliff, a boat has an angle of depression of 32°. Find how far the ladder is from the foot of the wall.the distance between foot of the ladder and the wall is 3.464 m.A string of a kite is 100 meters long and it makes an angle of 60° with horizontal. 110 m or 120 m are appropriate answers.

Now we need to find the distance between foot of the tower and the foot of the tree (BC).So, the distance between the tree and the tower is 51.96 m.Here BC represents height of the light house, AB represents the distance between the light house from the point of observation.
From the figure given above, AB stands for the height of the aeroplane above the ground. In the right triangle ABC the side which is opposite to angle 60 degree is known as opposite side (AB), the side which is opposite to 90 degree is called hypotenuse (AC) and the remaining side is called as adjacent side (BC). The three trigonometric ratios; sine, cosine and tangent are used to calculate angles and lengths in right-angled triangles. What is the height of the light house if A is 40 m from the base?A balloon is connected to a meteorological station by a cable of length 200 m inclined at 60 degree angle . (Imagine that there is no slack in the cable)Apart from the stuff given above, if you need any other stuff in math, please use our google custom search here. In the right triangle ABC the side which is opposite to the angle A is known as opposite side (BC), the side which is opposite to 90 degree is called hypotenuse side (AC) and remaining side is called adjacent side (AB).

Trigonometry index. Finding the Height of an Object Using Trigonometry Example: Two buildings are 300 ft apart. Calculate an estimate of the height of the building. Here AB represents height of the tower, BC represents the distance between foot of the tower and the foot of the tree. Angle of elevation.
