Answer:
m∠ACB = 82°
Step-by-step explanation:
m∠ACB = 180° - m∠ACD
∠ACB and ∠ACD are supplementary, which add up to 180°
m∠ACB = 180° - 98°

82
The horizontal line BD is a straight line bisected by the vertical line. Since it is a straight line, the two angles ACB and ACD must add up to 180.
So angle ACB is 180 - 98 = 82
