The combined amount of cats sold is 117.
Ratio expresses the relationship between two variables. It shows the frequency of which that one value is contained within another variable.
The ratio of Siamese cats to house cats = 4 : 9
Number of Siamese cats = 36
Number of combined cats = c
This equation can be formed using the above information:
4/13 x c = 36
4c = 468
c = 468 / 4
c = 117

I'm not sure is that right or wrong
Sin 167 = 0.22495
cos 107 = -0.29237
cos 167 = -0.97437
sin 107 = 0.95630
(sin 167)(cos 107) - (cos 167)(sin 107)
(0.22495)(-0.29237) - ( -0.97437)(0.95630)
= 0.86602
hope this helps :)
