Logan is a land surveyor. He wants to determine d, the distance across a lake that cannot be directly measured. He draws this diagram to help him.
d
7 km
9 km
What is the approximate distance across the lake, to the nearest tenth of a kilometer?

A 5.7
B6.3
C11.4
D16.0

the answer is 62

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

68719476736

step-by-step explanation:

8*8*8*8*8*8*8*8*8*8*8*8=68719476736

8 < i think

hope this !
