Answer:
89.44
Step-by-step explanation:
using the Pythagorean Theorem: [tex]a^{2} +b^{2}=c^{2}[/tex]
[tex]80^{2} +b^{2} =120^{2} \\6400+b^{2} =14400\\b^{2} = 8000\\b = 40\sqrt{5}[/tex]
120 is the hypotenuse so it would be c in the equation.
To solve, I simplified and isolated the variable. I got the square root of 8000 simplified (but idk how to write that out lol)
This answer is closest to 89.44
