Answer:
DBC = 75
Step-by-step explanation:
ABD and DBC are supplementary angles. They add to 180 degrees.
ABD + DBC = 180
105 + DBC = 180
Subtract 105 from each side
105-105 + DBC = 180-105
DBC = 75
Answer:
D
Step-by-step explanation:
the n th term ( explicit formula ) of a geometric sequence is
• 
= 
where r is the common ratio and the first term
here r = 
= 
= 
and = 64, hence
= 64
