Second one

 

This is a 30-60-90 right triangle

 

The  side across from the 30 degree angle  =  (1/2) * hypotenuse  = (1/2) * 6  =   3  =  y

 

 

Third one

 

In a 45-45-90 right triangle,  the hypotenuse is √2  times  either of the legs  =

 

5√2  =  r

 

 

Fourth one :

 

The side across from the 30 degree angle  =  3

x is across from the 90 degree angle in the second triangle    =  3√2
