Question

a man travelled 12 km due east from point p and reached a point q he travelled 5 km due south and reached r what distance would he have saved had he travelled directly from p to r​

Answer 1

Answer:

$pr = 13 \: km$

step by step explanation:

$pq = 12 \: km \\ \\ qr = 5 \: km \\ \\ by \: pythagoreas \: theorem \\ \\ {pq}^{2} + {qr}^{2} = {pr}^{2} \\ \\ {pr}^{2} = {12}^{2} + {5}^{2} \\ \\ pr = \sqrt{144 + 25} \\ \\ pr = \sqrt{169} \\ \\ pr = 13 \: km$
