Answer:

mAngleABC = 76°

Explanation:

AD is a diameter. So arcAD is half of the circle, that's 180°.

arcCD = 28°

arcAC + arcCD = 180°

arcAC + 28° = 180°

subtract 28°

arcAC = 152°

AngleABC is an inscribed angle (vertex is on the circle) so AngleABC is half of arcAC.

AngleABC

= 152 ÷ 2

= 76

AngleABC = 76°
