/ = divided -1/3(1) = -3 + 5 = 2 (g = 1)
Answer:3/2 or 1.5
Step-by-step explanation:
(9-6)/(3-1)=
3/2
8 sides
the exterior angle = 180° - 135° = 45° ( exterior/ interior are supplementary )
the sum of the exterior angles of a polygon = 360°
number of sides = 
= 8
Answer:
Step-by-step explanation:
That’s correct
Answer:
x = 10
Step-by-step explanation:
Consecutive angles in a parallelogram are supplementary, thus
∠ A + ∠ B = 180, substitute values
9x + 8 + 8x + 2 = 180, that is
17x + 10 = 180 ( subtract 10 from both sides )
17x = 170 ( divide both sides by 17 )
x = 10
