Answer:
(1;-2)
Step-by-step explanation:
x=-2y-3
2(2y+3)=-6y-9-5
10y=-20
y=-2
x=4-3=1

x=80 ft.
Area = x^2 = 80^2 = 6400 sq. ft.</span>


<em><u>Solution:</u></em>
<em><u>We have to find the inequalities that are true</u></em>
<em><u>Option 1</u></em>

0.6 is not less than 0
Thus this inequality is not true
<em><u>Option 2</u></em>

0.667 is greater than 0.5
Thus this inequality is true
<em><u>Option 3</u></em>

0.818 is less than 1
Thus this inequality is true
<em><u>Option 4</u></em>

0.5 = 0.5
Thus the above inequality is not true
Cos = adjacent over hypotenuse
cos33 = b/170
170cos33 = b
b = 142.574 inches
