Answer:
27.
Step-by-step explanation:
x/3 −9=0 Step 1: Simplify both sides of the equation. x/3 −9=0 1/3 x+−9=0 1/3 x−9=0 Step 2: Add 9 to both sides. 1/3 x−9+9=0+9 1/3 x=9 Step 3: Multiply both sides by 3. 3*( 1/3 x)=(3)*(9) x=27

Step-by-step explanation:
Answer:
6 sides
Step-by-step explanation:
the interior angle + the exterior angle = 180°
let x be the exterior angle then 2x is the interior angle and
x + 2x = 180
3x = 180 ( divide both sides by 3 )
x = 60
the exterior angle = 60°
the sum of the exterior angles of a polygon = 360°
since the polygon is regular the the exterior angles are congruent, then
number of sides = 360° ÷ 60° = 6
(5,1). you have to find the opposite of the x-coordinate. <span />
