Answer:
[tex]\sqrt{29}\ units[/tex]
Step-by-step explanation:
we know that
In a right triangle
Applying the Pythagorean Theorem
[tex]c^2=a^2+b^2[/tex]
where
c is the hypotenuse (the greater side)
a and b are the legs (perpendicular sides)
In this problem we have
[tex]a=2\ units\\b=5\ units[/tex]
substitute
[tex]c^2=2^2+5^2[/tex]
[tex]c^2=29[/tex]
[tex]c=\sqrt{29}\ units[/tex]
