The polygons are similar, but not necessarily drawn to scale. Find the value of x.

Answer:
13
Step-by-step explanation:
Two similar polygons have proportional corresponding sides. So,
[tex]\dfrac{x-3}{2.5}=\dfrac{8}{2}=\dfrac{16}{4}\\ \\\dfrac{x-3}{2.5}=4[/tex]
Solve this equation:
[tex]\dfrac{x-3}{2.5}=4\\ \\x-3=2.5\cdot 4\\ \\x-3=10\\ \\x-3+3=10+3\\ \\x=13[/tex]
Given that the two similar polygons, the value of x is determined as: 13.
Since the two given polygons are said to be similar, therefore, their corresponding side lengths are proportional to each other.
Thus:
(x - 3)/2.5 = 16/4
(x - 3)/2.5 = 4
x - 3 = 4 × 2.5
x - 3 = 10
x = 10 + 3
x = 13
Therefore, given that the two similar polygons, the value of x is determined as: 13.
