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

question 1: step-by-step explanation:

1/4 of 84 = 84÷4= 21

c minus thirteen equals negative two. to find c add thirteen two both sides. this cancels out the thirteen and gives you eleven on the other side. this leaves you with c equals eleven.
