Answer:

Step-by-step explanation:
CD is perpendicular to AB
If any radius or diameter is perpendicular to any chord of a circle, then it bisects that chord.
Mean, AB= BE = 12
So, AB = 2(BE)
2(12)= 24
so your answer will be 24

hope it helps..
have a great day!!
Answer:
B and D
Step-by-step explanation:
Make a line of best fit then find the slope and y intercept. put it into the y=mx + b form.
m=slope
b=y intercept
DC :AB=3:2 can be written as
DC/AB=3/2
Then you can get the answers easily
