Answer:
a). x = 5 inches
b). AB = 5 inches
c). BC = 15 inches
Step-by-step explanation:
From the given diagram, sum of the length of segment AB and length of segment BC will be equal to the length of AC.
That means, AB + BC = AC
Since AB = x inches
BC = 3x inches
and AC = 20 inches
A). x + 3x = 20
4x = 20
x = [tex]\frac{20}{4}[/tex]
= 5 inches
B). AB = x = 5 inches
C). BC = 3x = 3×5 = 15 inches
