in.
check answer

Explanation:

Step1: Calculate total length of 5 sides

$5 \times 3 = 15$ in

Step2: Find total length of remaining sides

$40 - 15 = 25$ in

Step3: Calculate length of each remaining side

A decagon has 10 sides, so remaining sides = $10 - 5 = 5$.
$\frac{25}{5} = 5$ in

Answer:

5 in.
