Question

. A lotus is 2m above the water in a pond. Due to wind the lotus slides on the side and only the stem completely submerges in the water at a distance of 10m from the original position. Find the depth of water in the pond

Answer 1

depth of pond= BC = x
bd= 10
cd = x+2

In Δbcd
cd² =bc² + bd²
(x+2)² = x² +10²

∴ x = 24

Answer 2

here CA=CD
Do you people know why?
it is just according to the given question
it is given that the stem CA fell 10 cm away from it's original position .therefore the stem CA completely merges 10 cm away from it and hence we know marked the stem as CD
