Q. 24.4( 7 Votes )

A man goes 80 m d

Answer :

The starting point of the man is A and the last point is B so we need to find AB. From the figure, ΔABC is a right triangle.

In a right angled triangle

(Hypotenuse) 2 = (Base)2 + (Height)2

where hypotenuse is the longest side.

(AB)2 = (AC)2 + (BC)2

AB2 = (80) 2 + (150) 2 = 6400 + 22500 = 28900

AB = 170 m
