For the figure shown, it is given that $\frac{K R}{R T} = \frac{K S}{S U}$ . Copy and complete the table.

Short Answer

Expert verified

The value of $K R = 8, R T = 4 and K U = \ grave 15$ .

Step by step solution

Step 1. Draw the given figure.

Step 2. Write down the given condition.

$\frac{K R}{R T} = \frac{K S}{S U}$

Step 3. Make the given table.

Step 4. From the table, write down the given values.

$K T = 12, K S = 10 and S U = 5$

Now,

$\begin{array}{l} \frac{K R}{R T} = \frac{K S}{S U} \\ \Rightarrow \frac{K R}{K T - K R} = \frac{10}{5} \\ \Rightarrow \frac{K R}{12 - K R} = \frac{10}{5} \\ \Rightarrow 5 K R = 120 - 10 K R \\ \Rightarrow 15 K R = 120 \\ \Rightarrow K R = 8 \end{array}$

And,

$\begin{array}{l} R T = K T - K R \\ = 12 - 8 \\ \Rightarrow R T = 4 \end{array}$

And,

$\begin{array}{l} K U = K S + S U \\ = 10 + 5 \\ \Rightarrow K U = 15 \end{array}$

Therefore, the value of $K R = 8, R T = 4 and K U = \ grave 15$ .
