Question 22.

Given:

• LQ = 9

,

• QP = 12

,

• LM = 6

• LN = x

Let's solve for x and MN.

Here, both triangles are similar.

To solve for the missing sides, apply the proportionality equation.

We have:


(LP)/(LQ)=(LM)/(LN)

• Where:

LP = LQ + QP = 9 + 12 = 21

• Input values into the equation and solve for x:


(21)/(9)=(x)/(6)

• Cross multiply:


\begin{gathered} 9x=21\ast6 \\ \\ 9x=126 \end{gathered}

• Divide both sides by 9:


\begin{gathered} (9x)/(9)=(126)/(9) \\ \\ x=14 \end{gathered}

The value of x = 14.

To solve for MN, we have:

LN = LM + MN

MN = LN - LM

MN = 14 - 6

MN = 8

ANSWER:

• Proportion to solve x:


(21)/(9)=(x)/(6)

• x = , 14

• MN = , 8
