Answer: 1080 degrees
Step-by-step explanation:
Since the general formular is
(n - 2 )180 = interior angle.
Where n is the number of sides the polygon has.
Octagon has 8 sides so therefore n= 8.
(8-2 ) * 180
= 6 * 180
=1080.
The total number of the interior angles measured is 1080 degrees.
Yes, it is a linear equation.
Answer:
x = 8
Step-by-step explanation:
Using the sine or cosine ratio in the right triangle and the exact value
sin30° =
, then
sin30° =
=
=
( cross- multiply )
x = 8
