Which construction requires drawing only one arc with a compass?

If we have to construct any thing like perpendicular bisector, angle bisector, any angle. For example the primary angle constructed in a 60° angle. But even to construct a 60° angle we need to construct two arcs.

Rest of all the constructions need at least 2 arcs to be constructed.

The only construction that can be done by only one arc is constructing a circle.

answer:   n ≤ -3 or n < -5

step-by-step explanation:

-5 + 2n ≥ -11

+5             +5

2n ≥ -6

2/2 ≤ -6/2

n ≤ -3

-6 - 10n > 44

+6           +6

-10n > 50

-10/-10 50/-10

n < -5

all it means is function 3
