Given:

There are given that the triangle ABC.

Explanation:

According to the given triangle:

We can see that the given triangle represents the proportionality theorem:

That means:

If a line parallel to one side of the triangle intersects the other two sides of the triangle, then the line divides these two sides proportionality.

Then,

From the given triangle:

\frac{CE}{EB}=\frac{CD}{DA}

Where,

\begin{gathered} CD=20 \\ DA=8 \end{gathered}

Then,

Put the value into the above proportionality:

So,

\begin{gathered} \begin{equation*} \frac{CE}{EB}=\frac{CD}{DA} \end{equation*} \\ \frac{CE}{EB}=\frac{20}{8} \end{gathered}

Then,

\begin{gathered} \frac{CE}{EB}=\frac{20}{8} \\ 8CE=20EB \\ CE=\frac{20EB}{8}...(1) \end{gathered}

Now,

We need to find the value for EB:

So,

For EB:

\begin{gathered} \frac{BE}{BC}=\frac{AD}{AC} \\ \frac{BE}{35}\frac{8}{28} \\ 28BE=280 \\ BE=10 \end{gathered}

Then,

Put the value of BE into the equation (1):

So,

\begin{gathered} \begin{equation*} CE=\frac{20EB}{8} \end{equation*} \\ CE=\frac{20(10)}{8} \\ CE=\frac{200}{8} \\ CE=25 \end{gathered}

Final answer:

Hence, the value of CE is 25.

Ilya [14]

Step-by-step explanation:

\:  \:  \:  \:  \: \frac{3}{10}  +  \frac{1}{3}  \\  \\  =  \frac{3 \times 3}{10 \times 3}  +  \frac{1 \times 10}{3 \times 10}  \\  \\  =  \frac{9}{30}  +  \frac{10}{30}  \\ \\   =  \frac{19}{30}  \\  \\ so \: as \: you \: see \: here \: we \: should \: put \: same \: denominator \\ \: for \: both \: fractions. \: hope \: this \: helps.. \\ good \: luck
