In the diagram |XY| = 12cm, |XZ| = 9cm, |ZN| = 3cm and ZY||NM, calculate |MY|
Attached Figure / Diagram
A
3cm
B
4cm
C
5cm
D
6cm
Verified Correct Answer: B.
Step-by-Step Mathematical Solution
\(\frac{|YM|}{|YX|} = \frac{|ZM|}{|ZX|}\)
\(\frac{|YM|}{12} = \frac{3}{9}\)
|YM| = 3 x \(\frac{12}{9}\)
|MY| = 4cm
