Answer:
From left to right picture,
Scale factor = 2/3
x = 24
y = 12
z = 21
Explanation:
Look at the two figures and identify the sides where both lengths are known.
That is the top right-hand side.
Scale factor is hence 18/27 = 2/3
Next, find x, y and z:
Bottom left-hand side: 16/x = 2/3
x = 3/2 x 16
x = 24
Bottom right-hand side: y/18 = 2/3
y = 18 x 2/3
y = 12
Top left-hand side: 14/z = 2/3
z = 3/2 x 14
z = 21
