what is the value of $x$ for which $m \parallel n$?
$x = 40$
$x = 5$
$x = 105$
$x = 30$
$105^\circ$
$(3x-15)^\circ$

Explanation:

Step1: Set angles equal (corresponding angles)

$3x - 15 = 105$

Step2: Isolate term with $x$

$3x = 105 + 15$
$3x = 120$

Step3: Solve for $x$

$x = \frac{120}{3}$

Answer:

x = 40 (Option: x = 40)
