Answer:
5.39 units
Step-by-step explanation:
Pythagorean theorem: [tex]a^{2} + b^{2} = c^{2}[/tex]
Let point (-2,1) be C
Line segment AC would be 2 units long.
Line segment BC would be 5 units long.
Insert the length of the line segments in to the Pythagorean theorem
[tex]2^{2} + 5^{2}[/tex]
4 + 25 = 29
[tex]\sqrt{29}[/tex] ≅ 5.385
