Similar shapes have sides with equal ratios to each other. To find each unknown side, compare its ratio to a known side.
For example, the ratio of the 15 mm side to the 22 mm side should be equal to the ratio of the z side to the
33 mm side.
z = 22.5 mm
You can now use the value of z to find ratios for the other unknown sides. Write two more ratios to solve for side x and side y.
15y = (22.5) (54)
y = 81 mm
What does x equal?
