Answer:
x > 38° only satisfies the condition.
Step-by-step explanation:
Given triangle ΔNPO, and ∠ PNM is the exterior angle to the interior angle ∠ PNO of the triangle.
So, ∠ PNM = ∠ NPO + ∠ PON
⇒ x = 38° + 39° = 77° {Given that ∠ PNM = 38° and ∠ PON = 39°}
{Since the exterior angle of an interior angle of a triangle is equal to the sum of the other two interior angles}
Hence, x > 38° only satisfies the condition. (Answer)
