Answer:
The answer to your question is x = 24 and y = 12
Explanation:
Data
ED = x HJ = 18
DF = 16 JG = y
EF = 20 HG = 15
Process
1.- Find x
Use proportions to find it
ED/EF = HJ/HG
Substitution
x/20 = 18/15
Solve for x
x = 20(18/15)
x = 360/15
x = 24
2.- Find y
JG/JH = DF/ED
Substitution
y/18 = 16/24
Solve for y
y = 18(16/24)
y = 288/24
y = 12
