Ignore where I marked 75 it was on accident but this is due tonight plz help

110°

NOTE: The calculations don't make sense when referred to the diagram. ∠4 is greater than ∠3 per calculation but the diagram seems to show ∠3 being greater so idk.

Step-by-step explanation:

The sum of all interior angles is 180°

Two angles are given, ∠1 and ∠2

180°=∠1+∠2+∠3

180=70+40+∠3

180=110+∠3

∠3=180-110

∠3=70°

∠3+∠4=180° Because it is a straight line.

180=70+∠4

∠4=180-70

∠4=110°
