Answer:
q = 27°
Step-by-step explanation:
the 155° angle and ∠ACB are supplementary angles. subtract 155 from 180 to get 25- ∠ACB is 25°.
since the sum of all angles in a triangle is 180°, we can set up this formula:
128° + 25° + q = 180°
simplify: 153° + q = 180°
subtract 153° from each side: q = 27°
