Answer: ↓↓↓
Explanation:
∠y and 86 are same-side interior angles / linear pairs so they are supplementary
∠y + 86° = 180°
∠y = 94°
∠x and ∠y are same-side exterior angles so they're also supplementary
∠x + ∠y = 180°
∠x + 94 = 180
∠x = 86°
Another way to find ∠x:
∠x and m∠86 are alternate exterior angles so they are congruent.
∠x ≅ 86
∠x = 86°
Hope that helped! Have a great day!
