Answer:
 180 degrees.
Step-by-step explanation:
Because the angle at the circumference is 90 degrees the arc joining the 2 other points = 180  degrees. 
So x = 360 - 180 = 180 degrees.

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
 the first term
here r =  =
 =  =
 =  and
 and  = 64, hence
 = 64, hence
 = 64
 = 64 → D
 → D
