Answer:
4
Step-by-step explanation:
Calculate the distance using the distance formula
d = √ (x₂ - x₁ )² + (y₂ - y₁ )²
with (x₁, y₁ ) = B(0, 0) and (x₂, y₂ ) = ([tex]\frac{\sqrt{6} }{2}[/tex], [tex]\frac{\sqrt{58} }{2}[/tex] )
AB = [tex]\sqrt{((\frac{\sqrt{6} }{2})^2 }[/tex] + [tex]\{(\frac{\sqrt{58} }{2})^2 }[/tex]
= [tex]\sqrt{\frac{6}{4} }[/tex] + [tex]\frac{58}{4}[/tex]
= [tex]\sqrt{\frac{64}{4} }[/tex]
= [tex]\sqrt{16}[/tex]
= 4
