Answer:
μ (∠1) = 82°
μ (∠2) = 98°
μ (∠3) = 82°
μ (∠4) = 98°
Explanation:
As the vertically opposite angles are equal to each other,
μ (∠2) = μ (∠4)
98° = 98°
As the angles in a straight line are added up to 180°,
μ (∠2) + μ (∠3) = 180
98 + μ (∠3) = 180
μ (∠3) = 180 - 98
μ (∠3) = 82°
As the vertically opposite angles are equal to each other,
μ (∠3) = μ (∠1)
82° = 82°
