Answer:

[tex]\sqrt{80} = c[/tex] is the answer.

Step-by-step explanation:

We can solve this using the Pythagorean theorem.

We know we can use the pythagorean theorem because it has a 90 degree angle.

[tex]a^{2}+ b^{2}= c^{2}[/tex]

We are given the sides 4 and 8.

[tex]4^{2} + 8^{2} = c^{2}[/tex]

[tex]80 = c^{2} \\\\\sqrt{80} = c[/tex]
