Step-by-step explanation:
Ans:A.
6×5÷2×11=165
In this case all you do is add all the numbers, answer is 100
it is c {-2,-1,2,5} lmk if it is wrong
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°
Simple...
you have: (2,3) and (-2,6)

Thus, your answer.
