This item can be answered by the concept of ratio and proportion. The ratio of the sculpture's height and shadow should be proportional or equal to that of the person. Mathematically,
6 ft / 2 ft = h / 4 ft
The value of h in the equation is 12 ft.
Answer:
B, Angle V is the smallest angle.
got it right on test
Complete the square
first isolate x terms
y=(x^2-4x)-9
complete square inside (take 1/2 of square of b )
-4/2=-2, (-2)^2=4
add 4-4 inside
y=(x^2-4x+4-4)-9
complete the square
y=((x-2)^2-4)-9
y=(x-2)^2-4-9
y=(x-2)^2-13
First, find angle ECD using tan^-1(6/4), we get angle as 56.31
Now by proportionate, angle ECD and angle EBA are equal.
Hence you can use tan to find AB i.e, AB = 18/tan(56.31)= 12
Therefore, AB = 12
