<MLN = <JLK = 39 degrees (vertical angles are equal)
If JK ║MN then <M = <K = 39 degrees (Alternate interior angles are equal)
In a triangle, sum of all interior angles = 180
61 + 39 +3x + 5 = 180
Combine like terms
3x + 105 = 180
subtract 105 from both sides
3x = 75
divide both sides by 3
x = 25
Answer
x = 25
