Answer:
4.5 m
Step-by-step explanation:
Distance from center to the the bottom part where headroom begins is 3.9 m-2.6 m=1.3 m
Since the radius is 2.6 m and acts as hypotenuse(see attached image), then the other length will be

Approximately 2.25 m
The half width is 2.25 m hence full width will be 2.25*2=4.5 m
Count backwards from 10 until you reach the number. for 8 you count 10,9,8 and for 3 you count 10,9,8,7,6,5,4,3. 8 is greater because it took <span>less </span>time to get there from 10. you could also count up from 0 (0,1,2,3 or 0,1,2,3,4,5,6,7,8). If you count from 0, the greatest is the one that takes the most amount of time
To find the correct option we need to calculate each of the given options.
Option (1):

Option (2):

Option (3):

option (4)
So, the correct answer is option (2)
Firstly, let's convert 10x + 2y = -2 to slope-intercept form (y = mx + b):
10x + 2y = -2
2y = -10x - 2
y = -5x - 2/5
The slope is -5. Parallel lines have the same slope; the question provides the y-int (12), so our equation is:
y = -5x + 12
Hope this helps.
