Answer:
font size of top line will be 1.067
Step-by-step explanation:
Scale factor between 4th line text size to the 3rd line text will be
= [tex]\frac{0.937}{0.878}=1.067[/tex]
Scale factor between 3rd line and second line will be = [tex]\frac{1}{0.937}=1.067[/tex]
Therefore, scale factor between 2nd and 1st text size will be = [tex]\frac{x}{1}=1.067[/tex]
x = 1.067
It reveals that the font size of top line will be 1.067
