Answer:
D) 45 ft
Step-by-step explanation:
The two triangles are shown below.
Given:
BC = 60 ft, CD = 24 ft and DE = 18 ft.
Since, the two triangles are similar, their corresponding sides are in proportion.
So, 
Now, consider the proportion of sides,

Therefore, the distance between A and B is 45 ft.
Answer:
D
Step-by-step explanation:
Just look for a pattern.
distance from -3 to 6 is 9
distance from 6 to 15 is 9
distance from 15 to 24 is 9
They're just adding 9 each time
24 plus 9 is 33
33 plus 9 is 42
42 plus 9 is 51
It’s not feet is numbers
Triangle a+b+c
Rectangle 2{l+w}
