To find the height of building, you observe that a yard stick held vertically on the ground cast a shadow of 4
831079
Then you measure the length of the shadow of the building (call it L)\n\nThe height of the building (H) is to 3 feet as the length of building's shadow is to 4 feet or\n\nH/3 = L/4 or H = 3/4 * L

It is slightly more than 127 feet.

there is one ninth of a square yard in a square foot.

The slope of the line is 3/4.

you count the legs and divide by 4

I can assist you in it. \n\nFirst draw a picture. On the left side of the picture draw a street lamp 6m. Then to the right of the picture draw a 2m man. Now draw a horizontal line AND a diagonal line connecting the top of the street light and man to the bottom of the horizontal line making a triangle. The part where the diagonal and horizontal meet is where the shadow is.Then along the horizontal line you see "x", and past the man is "s". \n\nNow form a formula.\n\nYou know that the street lamp is 6m tall and you want the distance from the bottom of the street pole to the end of the shadow and you know that the man is 2m tall and you want the distance to the end of the shadow so it is:\n\n6/(x+s) = 2/s\n\nCross multiply:\n\n6s= 2x+2s\n\nBring the 2s over:\n\n4s = 2x\n\nNow do the derivative:\n\n4(ds/dt)=2(dx/dt)\n\nYou know (dx/dt) = -1 so:\n\n4(ds/dt) = 2(-1)\n\n4(ds/dt)=-2\n\n(ds/dt) = -1/2 m/s.\n\nWhoo, that was a long question, but fun :D.

write a proportion (two equal fractions) with shadow on top and height on bottom, one for the tree and one for the meter stick:\n\n5/t = 0.4/1   where t = height of tree\n\nThen cross multiply

Sell the barometer and use the money to hire someone to find the answer.\n\nFind a point a which the barometer and the building have the same apparent height. Measure the distance from from eyeball to the barometer and the distance from your eyeball to the building. The ratio of the distances will equal the ratio of the heights. \n\nAt least I tried to give original answers!

Ex:\nA man stands 60 feet away from a building and sees the top of the building at a 60 degree angle. How tall is the bulding?\n \n1)Choosing an equation: (sin, cosine or tan)\nGoing to those three equations which one do we use?\nWell, we want to find the hight of the bulding (opposite b/c it is opposite the angle), so lets use tan.\n \n2)Setting the equation:\n \ntan 60 (the measure of the angle is θ) = (x) (opposite) / 60 (side adjacent to angle is adjacent)\n \n3)Press on Calculator: tan 60\n \nU should get: 1.732050...\n \n4) Multiply by 60. (b/c ur solving for x , see original equation),  \n5)Answer:  about 103.9230485\n \n6)Using 30-60-90 Triangle tricks we check our answer and find the height is 60 X (sqrt 3) which is aproximately 103.9230485 so we are right.

The slope is 1/3 and the point is (-2, -4).

The building's shadow is 52/4=13 times longer than Ben's shadow. Since the triangles are similar, the building will also be 13 times higher than Ben, i.e. 13*5, or 65ft.

The solidity of the ground. The ground was too soft to support the weigfht of the tower. The distribution of the towers weight on it's surface area required a more compact soil to be build upon. The engineers of that time didn`t have the means to predict this problem accuratly and hence the tower started leaning a fraction of an inch each year since the time it was built, untill it reached the weird inclination it has now.

No straight answer to this one. It depends 'exactly' what you define as a building, and whether you count masts and aerials that are on the top blah blah blah.\nHave a look here though for more information::

You need to solve this using similar triangles.\nOne triangle is formed by the meter stick and the shadow (it is a right triangle)\nThe other triangle is formed by the tree and the shadow of the tree.  \nThese triangles are similar because the meter stick and the tree are both being hit by the same angle of sunlight.\n\nSo now that you have similar triangles, you can set up a proportion.\n\nx/5 = 1/0.4\n\nThen you can cross multiply:\n0.4x = 5\nThen divide both sides by 0.4 (multiply by 2.5)\n\nx=12.5\nThe tree is 12.5 m tall

what is the pitch of the roof? 4:12?  use the pitch do determine the verticle  height per total horizontal foot. the hip comes after the roof height is determined.

probably to put up a taller building
