Answer:
The length of the hypotenuse is 6.4 units
Step-by-step explanation:
The complete question is
If the two legs of a right triangle are 5 and 4, what is the length of the hypotenuse?
we know that
Applying the Pythagorean Theorem
[tex]c^2=a^2+b^2[/tex]
where
c is the hypotenuse
a and b are the legs
we have
[tex]a=5\ units\\b=4\ units[/tex]
substitute in the formula
[tex]c^2=5^2+4^2[/tex]
[tex]c^2=41[/tex]
[tex]c=\sqrt{41}\ units[/tex]
[tex]c=6.4\ units[/tex]
