Step-by-step explanation:
Sum of exterior angle of any polygon is
360
o
.
As each exterior angle is
45
o
, number of angles or sides of the polygon is
360
o
45
o
=
8
.
Further as each exterior angle is
45
o
, each interior angle is
180
o
−
45
o
=
135
o
.
As there are
8
interior angles each
135
o
the sum of the interior angles of the polygon is
135
o
×
8
=
1080
o
