Answer:
3 in
Step-by-step explanation:
Sum of all sides of ∆ = perimeter
Given that it has a perimeter of 13 in, and the following sides: (x - 5) in, x/2 in, and 6 in, therefore:
Solve to find the value of x
Multiply both sides by 2
Subtract 2 from both sides
Divide both sides by 3
The shortest side = (x - 5) in
Plug in the value of x
= (8 - 5) in
= 3 in
