I don't get this at all.

 

Solve for x and y.

The small  triangle at  the bottom right  has  a base of  12

 

It is similar to the large  triangle such  that

 

(5 x - 1)  / 32   =    12/24   

 

(5x - 1)  / 32 =  1/2       cross-multiply

 

2 ( 5x - 1)  =  32

 

5x  -  1  =  32/2

 

5x  - 1   =  16

 

5x  = 17

 

x  =17/5

 

And the small triangle at  the  top  is  similar to the large triangle  such  that

 

(4y -3)   /( 32 - (5x - 1) ) =  24 /32

 

(4y -3)  / (32  -16)   = 24  / 32

 

 

(4y -3) / 16 =  12  / 16

 

4y  - 3  =  12

 

4y  =  15

 

y = 15/4

 

 

cool cool cool
