Answer:
6000 ft
Step-by-step explanation:
Let length of rectangular field=x
Breadth of rectangular field=y
Area of rectangular field= square ft
Area of rectangular field=
Area of rectangular field=
Fencing used ,P(x)=
Substitute the value of y
P(x)=
Differentiate w.r.t x
Using formula:
It is always positive because length is always positive.
Again differentiate w.r.t x
Substitute x=1500
Hence, fencing is minimum at x=1 500
Substitute x=1 500
Length of rectangular field=1500 ft
Breadth of rectangular field=1000 ft
Substitute the values
Shortest length of fence used=
Hence, the shortest length of fence that the rancher can used=6000 ft
Answer:
126°
Step-by-step explanation:
1. We know that 54 degrees and its adjacent are a linear pair, meaning that they add up to 180 degrees. To find the measure of the adjacent angle, we subtract 54 from 180.
2. Now, we know that adjacent of 54 is 126. Also, we know that ║
║ n, and x and 126 degrees are corresponding angles. Corresponding angles are congruent within angle measures, so x = 126 degrees.
