The answer is (4x20) + (4x4) which equals 96
4 is the answer, divide both sides by 3 and get 4
Answer:
The larger angle is 144 degrees and the smaller angle is 36 degrees
Step-by-step explanation:
Because this is a supplementary angle you have to find out what x is to solve this equation 
Because 2.4x and 9.6x are like terms we add them 
So now to find x we divide 180 by 12 to get 15
We replace the x with 15 
We add 36 and 144 which equals 180
Step-by-step explanation:
cross multiply all equations seperately
1,n=63
2.n=24
3.n=19
4.n=20
