Answer:
Height of the building = 77 ft.
Step-by-step explanation:
Let the height of the building (AB) = h feet
It's given that height of a woman (ED) = 5 feet 3 inches
                                                               ≈ 5 feet +  ft
 ft
                                                               ≈ 5.25 ft
Length of the shadow (BC) of the building = 55 ft
Length of the shadow (DC) of the woman = 45 in ≈ 3.75 ft
Since, both the triangles ABC and EDC are similar, their corresponding sides will be proportional.
By the property of similar triangles,


h = 
h = 77 ft
Therefore, height of the building will be 77 ft.

Answer:
Step-by-step explanation:
4/7 x + 70 cm^3 = 3/4 x          Subtract 4/7 x from both sides
3/4 x - 4/7 x = 70 cm^3          The lowest common denominator is 28

5x = 70*28
5x = 1960                                Divide by 5
x = 1960/5
x = 392 cc
