Answer:

x = 9√3

y = 18

Step-by-step explanation:

Using SOH CAH TOA

sin (thita) = Opp/hyp

sin 30 = 9/y

y = 9/sin 30

y = 9/0.5

y = 9×2

y = 18

Cos (theta) = Adj/hyp

cos 30 = x/18

x = 18×cos30

x = 18 × √3/2

x = 9√3

jolli1 [7]
I don't know if that is 100 tvs or one 100 inch tv. 

If it is 100 tvs then the person would have 301,800 dollars.
3,000 times 1000 plus 1800 equals= 301,800

If it is one 100 inch tv then the person would have 4,800 dollars
3,000+1800=4800.
