The area of rectangular is A= length x width
120 feet of fancing = ---------------------------------- (the above line)

x ! the enclosed area ! x

120 -(x+x)
so the area is A = (120-2x) (x)= 120x-2x²
Answer:
m∠A = 20°
Step-by-step explanation:
Triangle ABC has the following angle measures:
We know that the addition of the angles of a triangle makes 180°, therefore:
m∠A + m∠B + m∠C = 180°
Replacing with data and solving for x:
2x + 5x + 11x = 180
18x = 180
x = 180/18
x = 10°
Which makes the angles:
m∠A = 2*10 = 20°
m∠B = 5*10 = 50°
m∠C = 11*10 = 110°
Answer:
3x - 4 and 2x + 15
