We will count number of squares
first term is 4
so,
second term is 7
so,
third term is 10
so,
We can see that this sequence is in arithematic sequence
we can use nth term formula
where
an is nth terms
a1 is first term
d is common difference
n is total number of terms
now, we can plug values
and we get
.................Answer
2nd, 3rd, 5th, & 6th are the correct answers.
Answer:
The sixth angle of the hexagon is .
Step-by-step explanation:
A convex hexagon is one that does not have equal length of sides i.e it is irregular.
Sum of angles in a polygon = (n - 2) x 180
For an hexagon, n = 6.
Sum of angles in a hexagon = (6 - 2) x 180
= 4 x 180
=
Therefore, let the sixth angle be represented by x, so that;
+ + + + 3x + x =
+ 4x =
4x = -
=
x =
=
The sixth angle of the hexagon is .
Fifth angle = 3 x
=
