Answer 1

Hey Buddy

Here's The Answer

-------------------------------------------------

Firstly we construct a perpendicular line on BC , mark it as O.

NOTE :- REFFER THE ATTACHMENT FOR NAMING

So, Firstly we'll find AO by using ∆ AOC

We know

==> Sin ∅ = P/H

=> Sin ∅ = AO / AC

=> Sin 30° = AO / a

=> 1 / 2 = A0 / a

=> AO = a / 2

Now we'll find x by using ∆ AOD

==> Sin ∅ = P/H

=> Sin ∅ = AO / x

=> Sin 60° = ( a / 2 ) / x

=> √3 / 2 = ( a / 2 ) / x

=> x = ( a / 2 ) / ( √3 / 2 )

=> x = a / √ 3

So, option a / √3 is the correct answer

Hope it Helps
