Question

mathhhhhhhhhhhhhh >:(

Answer 1

so you use the theorem A^2 + B^2 = C^2 you use that equation to find the answer

Answer 2

let A,B,C be the three vertices.
CB=5-1=4
CA=4-1=3
\[AB^2=CB^2+CA^2\]
\[AB^2=3^2+4^2=9+16=25\]
\[AB=\sqrt{25}=5\]

Answer 3

Uhhh I don’t know I have an A in math but I still don’t know I have a hard time with Algebra
