Step-by-step explanation:

Since ∠E is right angle, its opposite side is DF and the legs are DE and EF.

Pythagorean applied:

  • [tex]DF^2 = DE^2+EF^2[/tex]

As per we know according to Pythagorean theorem

  • H^2=P^2+B^2

Here

  • H=DF
  • P=DE
  • B=EF

[tex]\\ \tt\hookrightarrow DF^2=DE^2+EF^2[/tex]
