Answer:
Yes; the compass was kept at the same width to create the arcs for points C and D.
Step-by-step explanation:
When bisecting a segment by hand the steps are:
-Place the compass on one of the endpoints and open the compass to a distance more than halfway across the segment.
-Swing an arc on either side of the segment.
-Keeping the compass at the same width, place the compass on the other endpoint and swing arcs on either side so that they intersect the first two arcs created.
-Mark the intersection points of the arcs and draw a line through those two points.
-The point where this new line crosses the given segment is the midpoint and divides the segment in half.
Its not b because segment c and d was created when you marked the intersection points of the arcs and just drew a line through those two points; They didn't use a straightedge. its not C because this does demonstrate how to bisect a segment by hand, Also the compass was kept at the same width to create the arcs for points C and D. Its not D because this does demonstrate how to bisect a segment by hand, Also a straightedge was not used to create segment CD.
2x-3y=13 equation (1)
x+2y=-4 equation (2)
multiply equation (2) by -2
-2x-4y=8 now we got equation (3)
Add equations(1) and (3) and combine like terms
2x-2x-3y-4y=13+8
-7y=21
y=-21/7= -3
substitute y with -3 in equation (2) and solve
<span>x+2(-3)=-4
</span>x-6=-4
x= -4+6
x=2
the solution for the system of equations is x=2, y= -3
X/360 * 3.14(6^2) = 45.27
When solved, x is about 144.1 when rounding to nearest the two decimal places.
The answer is 144.1 (I think)
1)72 feet squared
2) 14.28 feet squared
3) 30.6 feet squared
