35⁰
To solve for x, we need to find the sum of the interior angles of the hexagon and equate it to the known sum for a convex hexagon, which is 720°.
The sum of the interior angles is:
x° + x° + (2x - 3)° + (3x + 7)° + (7x - 12)° + (6x + 28)° = 720°
Expanding:
20x + 20 = 720
Subtracting 20 from both sides:
20x = 700
Dividing both sides by 20:
x = 35
So the value of x is 35.
