<h3>
Answer: x = 40</h3>
===================================================
Work Shown:
A+B+C = 180 ..... three angles of any triangle add to 180
(2x+10)+(x)+(2x-30) = 180
5x-20 = 180
5x = 180+20 .... adding 20 to both sides
5x = 200
x = 200/5 ... dividing both sides by 5
x = 40
This is the measure of angle B
We can stop here.
If you need to know the values of the other angles, then,
- angle A = 2x+10 = 2*40+10 = 90
- angle C = 2x-30 = 2*40-30 = 50
Then note how A+B+C = 90+40+50 = 90+90 = 180 which helps confirm our answer.

The width of the dug run is 73.5 ≤ w ≤ 237
<h3>What is a compound inequality?</h3>
A compound inequality is an inequality formed by combining two simple inequalities.
Analysis:
Let the width of dug run be w
perimeter = 2(67 + w) = 134 + 2w
281 ≤ 134 + 2w
147 ≤ 2w
73.5 ≤ w
Also, 134 + 2w ≤ 608
2w ≤ 474, w ≤237
In conclusion, the range of values of the width of the dug run is 73.5≤w≤237
