Question

Can anyone give me the answer?

Answer 1

applying the Pythagoras theorem to triangles ADB, BCD & ABC in that order,
225+a^2=b^2 ________1
144+a^2=c^2 ________2
b^2+c^2=729 ________3

Answer 2

subtracting eq 2 from 1,
b^2-c^2=81 _______4

Adding eq 3 & 4,
2b^2=810

Therefore, b=sqrt(405)
By knowing b, you can easily find out a & c

Answer 3

I'm still a little lost. @rajathsbhat

Answer 4

you ever measure the diagonals of a kite?

Answer 5

the segments of the diagonals multiply up equally such that we might have:

BD^2 = 12 * 15 if im seeing it right

Answer 6

i think that is also known as a geometric mean
