Question

1. in the figure, $jk = 5x + 7$, $kl = 7x + 2$ and $jl = 45$.

6a find $x$.
3
$x = 3$

6b find $kl$.
$kl = $

Explanation:

Step1: Recall the value of x

From part 6a, we found that \( x = 3 \).

Step2: Substitute x into KL's expression

The expression for \( KL \) is \( 7x + 2 \). Substitute \( x = 3 \) into this expression:
\( KL = 7(3) + 2 \)

Step3: Calculate the value

First, calculate \( 7(3) = 21 \), then add 2: \( 21 + 2 = 23 \).

Answer:

\( KL = 23 \)
