Supplementary means that the angles have to add up to 180, so you have your equation.
180=5x+17x-18
198=22x
x=9
Then to find the measures of the angles, you plug x back in.
m∠ABD=5(9)=45 degrees
m∠BDE=17(9)-18=153-18=135 degrees

Step-by-step explanation:
Answer:
29000, with the margin of error of ±5000
Step-by-step explanation:
Margin of error is the amount of error that can be caused due to variation, change of circumstances or any miscalculation.
In given case value of college student's debt can be between
24000 and 34000
Finding mid-point
(24000+34000)/2
29000
Now finding deviation of 29000 from 24000 and 34000
24000-29000= -5000
34000-29000= 5000
Hence
29000, with the margin of error of ±5000 !
