Answer:
127 degrees = x
Step-by-step explanation:
A six sided polygon has interior angles that sum to
(n-2)(180) = (6-2)(180 = 720
so all of the angles in the question add to 720
98 + 133 + x + x + 155 + 80 = 720
solve for x = 127 degrees
Answer:
x = 127
Step-by-step explanation:
the sum of the interior angles of a polygon is
sum = 180° (n - 2) ← n is the number of sides
here n = 6 , then
sum = 180° × 4 = 720°
sum the interior angles and equate to 720
x + x + 155 + 80 + 98 + 133 = 720 , that is
2x + 466 = 720 ( subtract 466 from both sides )
2x = 254 ( divide both sides by 2 )
x = 127
