Full turn = 360°
Number of 90° = 360 ÷ 90 = 4

Here too same procedure
4) 156 is the answer
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.
Answer:
Initial height of the anchor is 75 meters.
Step-by-step explanation:
We are given the following in the question:
where, I is the anchor's elevation in meter after t seconds dropped from the ship.
We have to find the initial height of anchor that is we have to put t = 0 in the equation.
Putting t = 0, we get,
Thus, initial height of the anchor is 75 meters.
Answer:
Perimeter = 31.4in
Area = 78.5in^2
Step-by-step explanation:
Perimeter -
2 x 5 x 3.14 = 10 x 3.14 = 31.4in
Area -
5 x 5 x 3.14 = 25 x 3.14 = 78.5in^2
