Given: |
CB = 12, CE = 4, AD = 5. |

Find: |
DB |

To determine

**To find:**

The side *DB *when the given sides are *CB *= 12, *CE *= 4, *AD* = 5 and

Explanation

**Definition:**

**CSSTP:**

Corresponding sides of similar triangles are proportional.

**Description:**

The given figure is shown below.

Figure 1

From the given figure, it is observed that there are two triangles *ABC *and *DBE* and which is given that two triangles are similar.

Now draw the two triangles separately as shown below.

Figure 2

Figure 3

Since

That is,

It is given that *CB *= 12, *CE *= 4, *AD* = 5.

Find the side *DB*.

Consider the first two pairs of proportions *DB*.

From Figure 1, it is observed that

Find *BE* by using the given values
