Answer: the answer is C
Step-by-step explanation: we know this because a straight line is 180 degrees. So given 140 degrees we know that g= 40.
61 miles per hour, because if you divide 183/3 you will get 61.
Angle ABD=87 degrees
angle ABC+angle CBD= angle ABD
Therefore, 9x-1+6x+58=87
15x+57=87
15x=87-57
15x=30
x=30/15
x=2
Angle ABC= 9x-1
=9(2)-1
=18-1
=17 degrees
