The 30º-60º-90º triangle is a special case you'd do well to remember, because the legs always occur in the same ratio to one another. As your picture shows (I'm guessing "SL" stands for short leg?), the sides labeled 4, y and x occur in a ratio of 1 to √3 to 2.
This means
sin(30º) = SL/(2*SL) = 1/2
tan(30º) = SL/(√3*SL) = 1/√3
(and also cos(30º) = (√3*SL)/(2*SL) = √3/2, though you don't really need that here)
So in this triangle, x and y satisfy
sin(30º) = 4/x
tan(30º) = 4/y
This comes straight from the definitions of sine and tangent. Then
4/x = 1/2 ==> x = 8
4/y = 1/√3 ==> y = 4√3

Step-by-step explanation:
Answer:
x = 6
Step-by-step explanation:
AD is a midline segment and divides EB and EC in the same proportion, that is
= 
Substituting in values gives
= 
= 
( cross- multiply )
5x + 2 = 32 ( subtract 2 from both sides )
5x = 30 ( divide both sides by 5 )
x = 6
Answer: divide the area buy the sides
