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°
138 x ? = 75
? = 75/138 = 0.544(3sf)
so about 54.35% (2dp) decrease
62.5 is your answer in decimal
