Answer:
D: 12
Step-by-step explanation:
The entire segment KI is composed of the segments KJ and JI. So:

We know that KI is 15.
KJ is (2x-15) and JI is (2x-6). Substitute:

Solve for x. Combine like terms:

Add 21 to both sides:

Hence, the value of x is:

We know that JI is 2x-6.
We will substitute 9 for x to find JI. So:

Hence, our answer is D.
Answer:

Step-by-step explanation:
Represent:
Phil's height with P
Suzanne's height with S
Phil's shadow with P1
Suzanne's shadow with S1
So, we have:



Required
Calculate the length of Phil's shadow --- Missing part of question
To do this, we make use of the following equivalent ratio.

Convert
to cm



Substitute values for P, S and S1

Express as fraction

Make P1 the subject





<em>Hence, the length of Phil's shadow is 24 cm</em>
