Answer:
7
Step-by-step explanation:
A quadrilateral, has 4 sides and its internal angles sum, add up to 360, now... you have 3 angles give.. .but we don't have C
so.. C is the difference of all the three angles from 360 or

whatever that is, now, you'll get some value in x-terms
so.... now once we know what C is
you can if you want, do a search in google for "inscribed quadrilateral conjecture", I can do a quick proof if you need one
but in short, for a quadrilateral inscribed in a circle, each pair of opposites angles are "supplementary angles", namely they add up to 180°
so.. what the dickens does all that mean? well D+B=180 and A+C = 180
now. we know what A is, 2x+1
and by now, you'd know what C is from 360-x-2x-1-148
so... add them together then and

solve for "x"
By definition the area of a rectangle is:
A = l * w
Where,
l: long
w: width
So we have to clear the width:
w = A / l
Substituting the values:
w = (234) / (18) = 13
w = 13 feets
answer
the width, in feet, of the room is 13
<h3>
Answer: 18 miles</h3>
Reason:
The path is 2 miles and Randy walked it 13 times. He walked a total of 2*13 = 26 miles.
Carla walked the path 22 times, so she walked a total of 2*22 = 44 miles.
The difference of those results is 44-26 = 18 miles.
If you wanted to do the full calculation in one line, then it would be
2*22 - 2*13 = 18
or you could say
2*(22-13) = 18
