Supplementary angles sum to 180 degree
Let one angle be x
Then the other angle is x+80
Summing the 2 angle gives
x+x+80=180
2x+80=180
2x=180-80
X=50
Thus the angles are 50 degree and 50+80= 130 degree
Answer:
6 : 7
Step-by-step explanation:
Total books = 52
Fiction books = 24
Non-Fiction = Total - fiction
= 52 - 24
= 28
Therefore, the ratio from fiction to nonfiction would be
fiction : nonfiction
= 24 : 28
Simplify
= 12 : 14
= 6 : 7
