Answer: 188+22x=518 (c)
Step-by-step explanation:
Assuming that you got the numbers right and that I did my calculations right, then the answer is <span>2998.45 tons.</span>
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
