Pay close attention, here

 

The triangle  on the left  is a 30-60-90   right triangle

 

The  sde opposite the 30°  angle  =   1

 

The side opposite the right angle [ the dashed line]  =   twice this  =  2 

 

And  the   triangle on the  right is also a 30-60-90  right triangle

 

The  angle  at the top right  vertex is the 30°  angle  in this triangle

 

And  the side opposite this = the dashed line  =  2

 

And  "x"  is opposite side  to the  right angle in this triangle so it's  twice as long as the dashed line =   4
