Not too sure on how to do this, all help is appreciated

Step-by-step explanation:

AB=2-(-5)=2+5=7

BC=√(3²+4²)=√(9+16)=√25=5

AC=√((6-(-5))²+(3²))=√(11²+3²)=√(121+9)=√130≈11.4

Perimeter=7+5+11.4=23.4 units

isaiah walks 3 miles due north, turns and then 5 miles due east. how far is he from his starting point?

a^2 + b^2 = c^2

let c = distance from starting point.

(3)^2 + (5)^2 = c^2

9 + 25 = c^2

34 = c^2

sqrt{34} = sqrt{c^2}

sqrt{34} = c
