Answer:
angle ABD=42°
Step-by-step explanation:
join AO with dotted line
AO=OD...radii
triangle AOD is an isosceles
angle DAO=angle ODA.....base angles of isosceles
angle DAO=48°
AngleAOD=180°-(48°+48°)....angle sum of triangle
=180°-96°
=84°
Angle AOD=2×angle ABD....angle at centre twice angle circumference
2xangle ABD=84°
Angle ABD=84°÷2
=42°
