(-3,-1) and contains (1,2).
The radius is given by:
We substitute the point to get:
Therefore any point that is 5 units from the center lies on this circle.
Answer:
a) = 8 in
b) When the length of AC = in. and BC =
in.
= 10 in
c) When the length of AB = 10.2 in. and BC = 3.7 in. = 6.5 in
d) When the length of AB = in. and BC =
in. in.
=
in
Step-by-step explanation:
a) When the length of AC = 5 in. and CB = 3 in. we have;
The length of = AC + CB (segment addition postulate)
Therefore;
= 5 in. + 3 in. = 8 in.
b) When the length of AC = in. and BC =
in. we have;
The length of = AC + CB (segment addition postulate)
Therefore;
=
in.+
in. = 10 in.
c) When the length of AB = 10.2 in. and BC = 3.7 in. we have;
The length of = AB - BC (converse of the segment addition postulate)
Therefore;
= 10.2 in.+ 3.7 in. = 6.5 in.
d) When the length of AB = in. and BC =
in. in. we have;
The length of = AB - AC (converse of the segment addition postulate)
Therefore;
=
in. -
in.=
in.
