Answer:

4.47

Explanation:

Using Pythagorean's theorem, we know that
a^(2) +
b^(2) =
c^(2).


c^(2) is the hypotenuse which is what we are trying to figure out.


a^(2) and
b^(2) are the measurements of the legs.


4^(2)+
2^(2) =
c^(2)


4^(2)= 16


2^(2)=4

16 + 4 = 20

20 =
c^(2)


√(20) =
\sqrt{c^(2) }

2
√(5) = 4.47

Answer: 4.47

Explanation:

Hello there!

Use the Pythagoream theorem:


a^(2) +b^(2) =c^(2) \\4^2+2^2=c^2\\16+4=20\\x=√(20) \\x=4.472135
