6-a man standing in a valley between two parallel mountains fires a gum and hears echo at an mterval of 2 s and
3.55. what is ;
(a) the distance between two mountains
(b) the location of the man with respect to the mountain. (speed of sound - 334 m/s)

you need to show the graph

step-by-step explanation:

the median is   36 orr sum like dat

step-by-step explanation:

answer: (-8,4) are the coordinates of a

step-by-step explanation:

let the side of square abcd is x .

thus the area of square abcd is .

now, by the diagram area of triangle ead= 1/2 × ea × ad = 1/2 × ea × x

( because ad is the side of square)

and, according to the question,

the areas of square abcd and right ead are equal.

⇒

⇒ea=2x

thus, ea: ab=2: 1

therefore, point a divides line segment eb into the ratio 2: 1.

⇒ by sectional formula coordinates of a are,

=

=

=(-8, 4)

thus the coordinates of a are (-8,4)
