# In Exercises 25 to 28, Δ A B C ∼ Δ D B E Exercises 25-28Given AC = 8, DE = 6, CB = 6.Find: EB(HINT: Let EB = x, and solve an equation.)

To determine

To find:

The side EB when the given sides are AC = 8, DE = 6, CB = 6 and ΔABCΔDBE.

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 ΔABCΔDBE and from the definition of CSSTP, corresponding sides of similar triangles are proportional.

That is, BDBA=BEBC=DEAC.

It is given that AC = 8, DE = 6, CB = 6.

Find the side EB.

Consider the last two pairs of proportions BEBC=DEAC in order to find EB
