Answer:
The vertex is the point (4,3)
Step-by-step explanation:
we have
Convert to vertex form
Group terms that contain the same variable, and move the constant to the opposite side of the equation
Factor the leading coefficient
Complete the square. Remember to balance the equation by adding the same constants to each side.
Rewrite as perfect squares
----> equation in vertex form
The vertex is the point (4,3)
MAB is 120, so m∠ADB is half of mAB=60
AC is the diameter, which means arc ABC is 180, and m∠ADC=90
m∠BDC=m∠ADC-m∠ADB=90-60=30
so the angle BDC is 30 degree
