Answer:

(5[tex]\sqrt{2}[/tex])/2

Step-by-step explanation:

sin = opp/hyp

sin(45) = x/5

[tex]\sqrt{2}[/tex]/2 = x/5

x = (5[tex]\sqrt{2}[/tex])/2

Answer:

  • C.  [tex]5\sqrt{2}/2[/tex]

Step-by-step explanation:

Property of a 45° right triangle:

  • c = a [tex]\sqrt{2}[/tex], where c- hypotenuse, a - one of legs

Apply to the given:

  • 5 = x [tex]\sqrt{2}[/tex]
  • x =  [tex]5/\sqrt{2}[/tex] or
  • x =  [tex]5\sqrt{2}/2[/tex]

Correct choice is C
