x+12=8

Answer:

$m\angle N=57^{\circ}$

Step-by-step explanation:

From the isosceles-base theorem, the measure of the angles adjacent to the pair of congruent sides of the triangle are equal. Since the problem declares $LM\cong LN$ , the remaining unknown angles are equal ( $m\angle N=m\angle M$ ). The sum of the interior angles of a triangle always add up to $180^{\circ}$$ .

Therefore:

$m\angle N\cdot 2+66=180,\\m\angle N\cdot 2=114,\\m\angle N=\fbox{$57^{\circ}$}$ .
