Answer:
x = 7.5
Step-by-step explanation:
A line parallel to a side of a triangle and intersecting the other 2 sides, divides those sides proportionally, that is
[tex]\frac{8}{10}[/tex] = [tex]\frac{6}{x}[/tex] ( cross- multiply )
8x = 60 ( divide both sides by 8 )
x = [tex]\frac{60}{8}[/tex] = 7.5
