Answer:
110°
Step-by-step explanation:
Adjacent angles in a parallelogram are supplementary:
∠L +∠O = 180°
(2x +10) +(x +20) = 180
3x = 150 . . . . . . . . . . . . . subtract 30
x = 50
Then ...
∠L = (2x +10)° = (2·50 +10)° = 110°
Opposite angles in a parallelogram are congruent, so ...
∠N = ∠L = 110°
