Answer:

m∠2 = 95°

m∠3 = 85°

m∠4 = 95°

Explanation:

Vertical Angle Theorem:

When two straight lines intersect, the opposite vertical angles formed are always equal (congruent) to each other.

Therefore,

m∠3 = 85°

m∠2 = m∠4

Linear pair:

Two adjacent angles which, when combined, form a line, so the sum of a linear pair is 180°.

Therefore,

85° + m∠2 = 180°

m∠3 + m∠4 = 180°

If 85° + m∠2 = 180°

⇒ m∠2 = 180° - 85°

m∠2 = 95°

As m∠2 = m∠4 then m∠4 = 95°
