Answer :

Answer:

x = 32 mm

Step-by-step explanation:

Given the triangles are similar , then the ratios of corresponding sides are in proportion.

x and 8 are corresponding sides

20 and 5 are corresponding sides

Then

[tex]\frac{x}{8}[/tex] = [tex]\frac{20}{5}[/tex] = 4 ( multiply both sides by 8 )

x = 8 × 4 = 32 mm
The answer is 20\5 that would be 4 in simple form
