I can help if you put the number sentences in
Y/x = 9/12 = 3/4
so
y = (3/4)x . . . . . . both x and y in dollars.
Cot x= cosx/sinx =√3
tan x= 1/ √3
cos x = √2 /2
x= 45
tan45= 1
tan x= -4/3
csc x= 13/5
1/sin x = 13/5
sin x= 5/13
x=22.62
tan x= 5/12
It would be written as 721/10. Hope this helps.

They only have 3 and two in common when you fully factor them. 3×2= 6
6 is the greatest common factor.
