Answer:

x = 2.2

Step-by-step explanation:

From the figure, we see that

Δ ABC

is similar to

Δ ADE

So we can say that the corresponding sides are proportional (ratio is equal).

From the similarity statement, we can say:

AB corresponds to AD

BC corresponds to DE

AB = 10

AD = 10 + 1 = 11

BC = 2

DE = x

Now, we can write ratios and solve:

\frac{AB}{BC}=\frac{AD}{DE}\\\frac{10}{2}=\frac{11}{x}\\10x=2*11\\10x=22\\x=\frac{22}{10}\\x=2.2

The value of x is 2.2
