Answer: find x
Tan(30)=20/x
X= 20/ tan(30)
Tan(30) =0.577
X= 20/ 0.577
X=34.66
Find Y
Sin(30)=20/y
Y=20/sin(30)
Sin(30)=0.5
Y=40

Among the given numbers, 
We have two numbers, which are 22/7 and 
Both of the numbers are irrational numbers, they are nonrepeating and nonterminating.
A fraction written in a particular way is called decimal form.
Now, evaluating both the given numbers in decimal form, we get,
22/7 = 3.14
and 
Now, Clearly, 4.12 > 3.14
Thus,
