Question

find the value of X​

Answer 1

Step by step explanation:

Let F is any point lying between CD..

And let distance betwewn EF is y m

Clearly,We will apply Tan

In ∆ EDF

Tan 60°°=EF/AF

√3=28.5/y

y=28.5/√3 (By rationalizing)

y=28.5x√3/√3x√3

y=28.5√3/3

y=9.5√3 (i)

We will apply tan again

In ∆ADF

Tan30°=DF/AF [AF=AE+EF]

1/√3=28.5/x+y

x+y=28.5√3

Putting value of y from eq(i)

x+ 9.5√3=28.5√3

x=28.5√3-9.5√3

x=19.5√3m

or 19.5 x 1.732=33.774m(Approx.)
