Answer:
The answer to your question is letter D
Step-by-step explanation:
Formula
                      m∠E = 
Data
m∠E = 48°
DGF = 228°
DF = x°
Substitution
                     48° = 
Solution
                                      2(48) = 228 - x°
                                      96 = 228 - x°
                                      96 - 228 = - x°
                                     - 132 = - x°
                                        x° = 132°
 
        
             
        
        
        
An=a1r^(n-1)
given
a5=1/24
a10=1/768
we know that
a5=1/24=a1r^(5-1) and
a10=1/768=a1r^(10-1)
so
1/24=a1r^4
1/768=a1r^9
(a1r^9)/(a1r^4)=r^5=(1/768)/(1/24)=1/32
r^5=1/32
take 5th root of both sides
r=1/2
we have
a5=a1r^4=1/24
evaluate r^4 or (1/2)^4
1/16
a1(1/16)=1/24
times both sides by 16/1
a1=16/24
a1=2/3
the first term is 2/3
