Question

friends plzz solve this it's so important ​

Answer 1

answer is a/4. this your answer

Answer 2

Let AB = a be the line joining feet of the persons and C be the mid-point of this line.

Also, let h be the height of the shorter person, then height of the taller person will be 2h

From figure,

tanx = h/a2 = 2h/a..

Also,

tanx(90-x)2h/a/2=4h/a=cotz..(2)

Multiplying and , we get

tanx × cotx = 8h²/a² =1

a²x=8h²

h = a/2√2

which class r you ?
