A. 5/8 = h/20
Step-by-step explanation:
Topic: Triangle Similarity
As you can see in the image you can paint the problem that way, it means that each side of the triangle is a multiplier from the other one same side, so you can build a relation as follows:
[tex]\frac{5}{h} = \frac{8}{20} \\[/tex]
you can re arrange the equality as
[tex]\frac{5}{8} = \frac{h}{20}[/tex]
as you can ssee you just reached the option A. 5/8 = h/20
