Answer:
No, they are not copies of each other.
Step-by-step explanation:
<XNY and <ZHC are not the same sized angles. The shapes would have the same angles if they were just scaled down copies.
Let's put it into perspective.
x/(x+5)
If increase by 3:
(x+3)/(x+8) = 3/4
Cross multiply.
4(x+3)=3(x+8)
4x+12 =3x+24
Solve algebraically.
4x-3x = 24-12
x = 12
Therefore, original fraction is:
12/17
