Question

the measure of angle jkl can be represented using the expression 3x + 5. what is the degree measure of ∠jkl?

Explanation:

Step1: Set up equation

$3x + 5=45 + x$

Step2: Solve for x

$3x - x=45 - 5$
$2x = 40$
$x = 20$

Step3: Find angle JKL

Substitute $x = 20$ into $3x + 5$.
$3\times20+5=60 + 5=65$

Answer:

$65$
