Answer 1

Answer:

we know, the height of tree, = 12m

let the height of tree from the bottom broken by wind be 'x'm.(horizontal)

Thus,

height of tree(from borken part to top)=(12–x)m

Angle of elevation=60°

√3=1.732

To find- value of x.

In the ∆ formed respectively,

as, sin∅=opp.side/hypotenuse

sin60°=(x)÷(12–x)

√3/2=(x)÷(12–x)

12√3–√3x=2x

2x+√3x=12√3

x(2+√3)=12√3

x=(12√3)/(2+√3)

x=24√3–36 (on rationalising the denominator)

x=41.568–36 (as, √3=1.732)

x=5.567m
