Answer:


m \angle 1= \boxed{159}\;^(\circ)\\\\m \angle 2= \boxed{21}\;^(\circ)\\\\m \angle 4= \boxed{21}\;^(\circ)

Explanation:

Angles on a straight line sum to 180°.

⇒ m∠3 + m∠4 = 180°

⇒ 159° + m∠4 = 180°

⇒ m∠4 = 21°

Vertical Angle Theorem

When two straight lines intersect, the opposite vertical angles are congruent.

Applying the Vertical Angle Theorem:

  • m∠1 = m∠3 = 159°
  • m∠2 = m∠4 = 21°
