Answer:
The measure of the interior angle C is
.
Step-by-step explanation:
Sum of angles in a polygon = (n - 2) x 180
where n is the number of sides of the polygon.
For a hexagon, n = 6. So that;
Sum of angles in a hexagon = (6 - 2) x 180
= 4 x 180
= 
Sum of angles in a hexagon = 
⇒ 3x + 15 + 2x + 30 + 5x + 10 + 2x + 55 + 2x + 60 + x - 35 = 
15x + 135 = 
15x =
- 135
15x = 585
x = 
= 
But,
C = 2x + 30
= 2(39) + 30
= 78 + 30
= 
The measure of the interior angle C is
.
