Hi,The answer to your question is down belowThe width measures 10 feet.
Let the length be x and the width be <span>x−10</span>.
Since the pool is rectangular:
<span>A=L×W</span>
<span>200=x<span>(x−10)</span></span>
<span>200=<span>x2</span>−10x</span>
<span>0=<span>x2</span>−10x−200</span>
<span>0=<span>(x−20)</span><span>(x+10)</span></span>
<span>x=20and−10</span>
A negative answer is not possible, so the width of the pool is <span><span>(20−10)</span>=10</span> feet.

A or B Is the answer I hoped this eliminated your choices a little<span />
5x-3y=16
3x-5y=-4
Multiply the first equation by 3; the second one by 5
15x-9y=48
15x-25y=-20
Eq 1 - Eq 2:
-9y+25y=48+20=68
16y=68
4y=17
y=17/4
5x-3y=16
5x-3×17/4=16
5x=16+51/4=(64+51)/4=115/4
x=115/4/5=23/4
x=23/4
Answer:
x=36° (180/5x because 2x+3x)
