Given that a
= 14 cm and
b
= 7 cm, work out
x
.
Give your answer as an exact surd in its simplest form.

15.65

Step-by-step explanation:

7^2+14^2

49 + 196 = 245

245=c^2

15.65

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
