A 6 foot tall man makes a shadow that is 3 feet long. How tall is a building that makes a 14 foot shadow?

[A] Write a proportion that is defined by this situation.

[B] Explain how the cross product is used to solve the problem.

[C] Answer the question.

A) 1 : 12/7

B) see explanation below

C) 25.5 feet

Step-by-step explanation:

6 : 3.5 --> 1 : 12/7

x : 14.875 -->  1 : 12/7

x= (14.875) (12/7)

x=  25.5

m1=5,m2=0

compare the two slopes in the decimal form. if the slopes are equal, then the lines are parallel. if the slopes are not equal, then the lines are not parallel.
