Answer 1

∠1 = 36°

∠2 = 122°

∠3 = 122°

∠4 = 38°

Explanation:

∠2 = 180°-58° (Supplementary angles add up to 180°)

= 122°

∠2 = ∠3 (Vertically opposite angles are equal)

= 122°

∠1 = 180°-122°-22° (Sum of angles in a triangle is 180°)

= 36°

∠4 = 180°-122°-20° (Sum of angles in a triangle is 180°)

= 38°
