Question

I need help on this please

Answer 1

82

Explanation:

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

Answer 2

m∠ACB = 82°

Explanation:

m∠ACB = 180° - m∠ACD

∠ACB and ∠ACD are supplementary, which add up to 180°

m∠ACB = 180° - 98°

m∠ACB = 82°
