Solution
38.07 metres, South-East
Explanation:
A = starting point of Pratham
C = end point of pratham
Distance between AC = `sqrt ("AB"^2 + "BC"^2)`
`=sqrt((15)^2 + (35)^2)`
`= sqrt(225+1225) = sqrt 1450` = 38.07 m
Therefore pratham is 38.07 m far from his original position and point C, which is end point is south- east from hos starting point A.
