Question

Adam and Betty start are the same point Adam walls 3 feet north while Betty walks 4 feet west. If a straight line were to be drawn between Adam and Betty How would that lime be

Answer 1

Answer:

5 feet.

Step-by-step explanation:

i) Adam walks 3 feet north

ii) Betty walks 4 feet west.

iii) We know that the angle between north and west is 90 degrees.

iv) Therefore we can say that distance Adam walks is the height of a right

    angled triangle and the distance that Betty walks is the base of the right  

  angled triangle.

v) Therefore by using Pythogoras's Theorem we can calculate the length of

   the line between Adam and Betty as shown

  length of line between Adam and Betty = $\sqrt{3^{2} + 4^{2} } = \sqrt{9 + 16} = \sqrt{25} = 5$ feet.
