From the given information, we see that the building and its shadow form a right triangle with base 30 ft and height 55 ft.Also, the person and his/her shadow form another similar triangle with base 3 ft and height x ft.Since both triangles are similar, we have:x/55 = 3/30 orx/55 = 1/10 cross multiply10x = 55 divide by 10 to both sidesx = 5.5Thus the person is 5.5 inches tall.
It is: 27.35 degrees rounded to two decimal places
Let x be the height of the boy and seeing that they both have the same tangent ratio so it must follow that: x/3 = 11/19 Multiply both sides by 3 and then divide the product by 19: x = 1.736842105 Therefore height of boy = 1.7 meters to the nearest tenth.
If you mean the height of the building then it works out as 466.5063509 feet
Using trigonometry the angle of elevation is 77 degrees rounded to the nearest degree
(Height of the building)/(length of the shadow) = tangent of 31° .Height = 73 tan(31°) = 43.9 feet (rounded)
If the building casts a shadow, then the sun is out, and any man who is not standing in theshadow of the building will cast a shadow of his own, no matter how short or tall he may be.(If you had told us the length of the man's shadow, it would have been a completely differentquestion, and we could have had a completely different answer to offer in response.)
Let x = the height of the building. So we have, x/2.6 = 42.25/1.51 x = (2.6)(42.25)/1.51 x =72.75 Thus, the building is 72.75 meter tall.

If you are standing at the South Pole, your shadow will be non-existent during the summer solstice when the sun is directly overhead. During other times of the year, your shadow will be longer compared to standing at other latitudes due to the angle of the sun in relation to the Earth's surface. The length of your shadow will vary depending on the time of day and the season.

as long as your'e standing in sunlight
To cast a 19 foot shadow the building would have to be 26.91 feet tall. Each foot of building/tree casts 8.47 inches of shadow.

It sounds like a homework question, so I am going to act like a tutor. What you need to do is convert the height of the building and the shadow into inches. Fifty three feet three inches is equal to how many inches? 30 feet is equal to how many Inches? Then all you have to do is figure out the ratio (larger number divided by smaller number in this case) and multiply that by the height of the shadow of the man) Then you might want to convert back into feet and inches. Hint: the building is taller than its shadow, so the man also will be taller than his shadow.
