Answer:
the answer is [tex]\sqrt{17}[/tex]
Step-by-step explanation:
the Pythagorean theorem is [tex]a^{2}[/tex] + [tex]b^{2} = c^{2}[/tex]. c is always the hypotenuse (the longest side) and a and b are the legs (the shorter sides) so 1 squared plus 4 squared is 17. there is no whole square root of 17 so the answer is [tex]\sqrt{17}[/tex]
