Answer:
x=4
,y=8
Step-by-step explanation:
sin∠SRT = sin∠TSV,
SO 
, 
=80,x=
;
In the same way:
sin∠RSV = sin∠RTS,
SO 
，
=320,y=8
4/7 of the children in the pool are girls
3/7 of the children in the pool are boys
4/7:3/7
4:3 is the ratio of girls to boys
So you wanna find the area of each surface:
For the large square surface in the top you do 12*15=180 and there are two large squares faces so you multiply 180 by 2 which equals 360 then you find the small rectangle faces: 5*15=75 and multiply by 2 Bc there are 2 faces like that so it would be 75*2=150 then for the last faces you do 12*5= 60 *2= 120 at the end I add all of the faces up, 360+150+120=630
