The angle of elevation to the top of a Building in New York is found to be 8 degrees from the ground at a distance of 1 mile from the base of the building. Using this information, find the height of the
building.

step-by-step explanation:

given that there are two triangles j'k'l' and jkl>

the former is got by dilating the second one.

when drawn on a grid, (graph paper) coordinates of vertices of first triangle is

(6,12)j, (9,6)k and (12,9)l

side jk has length = distance between j and k

=

side j'k'=distance between j' and k'

=

ie j'k'l' has sides 1/3 of that of corresponding sides of jkl.

hence scale factor of 1/3 is used to get j'k'l'from jkl

180-142=38 for the acute angle next to the entry

90+38=128

180-128=52

a=52
