**Step-by-step explanation:**

<u>Concept:</u>

Here, we need to know the idea of similar triangles.

Two triangles are similar if they have the same ratio of corresponding sides and equal pairs of corresponding angles.

If you are still confused, please refer to the attachment below for a graphical explanation.

<u>Solve:</u>

<em>Set up the proportion between the sides</em>

Small / Big = Small / big

10 / 22 = y / 33

<em>Cross-multiply to simplify the proportion</em>

22 · y = 33 × 10

22y = 330

<em>Divide 22 on both sides</em>

22y / 22 = 330 / 22

y = 15

Hope this helps!! :)
