9=5 -y/3
-5
3=-y/3
cross multiply
1=-y
y=-1
Supplementary angles sum up to 180°, suppose the supplement of 161° is x. Then
161+x=180
solving for x we subtract 161 from both sides
161-161+x=180-161
x=19
thus the supplement is 19°
So just add all of them together and you get 405. Then divide by the amount of numbers there is which is 5. So 405 divided by 5. The answer is 81.
Answer:
The only problem was that now it costs more so not really
Step-by-step explanation:
I think its an opinion question
Answer: B.
Step-by-step explanation: These are the multiples of 15 but what you are probably asking or what are the factors of 15. If ABCD and EFGH are similar, then you should be able to line up corresponding points (for example, A corresponds to E, B corresponds to F). if they're different sizes, you should then dilate one of them so that they are the exact same size.
