Answer:

Henry and Valencia are 16 m apart.

Step-by-step explanation:

A sketch to this question shows that their distance apart forms a right angled triangle. So then, we can apply the Pythagoras theorem.

Let the distance between Henry and Valencia be represented by x, so that;

[tex]/hyp/^{2}[/tex] = [tex]/adj 1/^{2}[/tex] + [tex]/adj 2/^{2}[/tex]

[tex]20^{2}[/tex] = [tex]x^{2}[/tex] + [tex]12^{2}[/tex]

400 = [tex]x^{2}[/tex] + 144

[tex]x^{2}[/tex] = 400 - 144

   = 256

x = [tex]\sqrt{256}[/tex]

  = 16

x = 16 m

Therefore, Henry and Valentia are 16 meters apart.
