Answer:
Step-by-step explanation:
We have two points
(
6
,
8
)
and
(
−
2
,
0
)
Explanation:
To find number of points of intersection, we should solve these pair of equations.
As
y
=
x
+
2
, we have
2
x
2
−
(
x
+
2
)
2
=
8
or
2
x
2
−
x
2
−

x
−
4
=
8
or
x

−

x
−

=
0
or
x

x
−

x
−
12
=
0
or
x
(
x
+
2
)
−
6
(
x
+
2
)
=
0
or
(
x
−
6
)
(
x
+
2
)
=
0
and hence
x
=
6
or
−
2
putting these values in
y
=
x
+
2
, we get
y
=
8
or
0
Hence, we have two points
(
6
,
8
)
and
(
−
2
,
0
)

Answer:
The number of sides the polygon have 9
Step-by-step explanation:
Given in question as :
For The circle , the central angles measure be 40 °
Let the number of sides of polygon = n
Now . as we know
External angle =
Or , 40° =
Or, = 40°
Or, = 40°
So, n = = 9
Hence The number of sides the polygon have 9 Answer
Add the ratio together: 5:4 becomes 5+4 = 9
divide the amount by 9:
54 / 9 = 6
multiply 6 by both 5 and 4
6 *5 = 30
6 * 4 = 24
30 and 24 are two amounts
