Answer:
x = 22.5°
3x = 67.5°
5x = 112.5°
7x = 157.5°
Explanation:
You have both 2° and x for the measure of the first angle. I used x°.
Sum of the measures of the interior angles of a polygon
For an n-sided polygon:
(n - 2)180° = 2(180°) = 360°
x° + 3x° + 5x° + 7x° = 360°
16x = 360
x = 22.5°
3x = 67.5°
5x = 112.5°
7x = 157.5°
