Help me with this please!!!!!!!!!!!!!!!!!!!!!

Answer:
y = 2 units
Step-by-step explanation:
We can solve this in 2 ways, both ways would give the same answer:
#1) Sin(45) = [tex]\frac{\sqrt{2} }{y}[/tex]
=> Sin(45) * y = [tex]\sqrt{2}[/tex]
=> y = [tex]\frac{\sqrt{2} }{Sin(45)}[/tex]
=> y = 2
#2) Cos(45) = [tex]\frac{\sqrt{2} }{y}[/tex]
=> Cos(45) * y = [tex]\sqrt{2}[/tex]
=> y = [tex]\frac{\sqrt{2} }{Cos(45)}[/tex]
=> y = 2
Hope this helps!
