A regular nonagon is 9-sided polygon with all congruent sides and congruent interior angles.
The sum of exterior angles of n-sided polygon is 360°. If all interior angles of regular nonagon are congruent, then all exterior angles are congruent too.
Then each exterior angle has the measure of
Answer: 
Answer: 3x - 146
Step-by-step explanation:
Add all "x" and numbers
3x - 122 - 32 + 1 + 7
3x - 154 + 8
3x - 146

Answer:
(6, - 3 )
Step-by-step explanation:
Given the 2 equations
2x + 5y = - 3 → (1)
2x + 2y = 6 → (2)
Subtracting (1) from (2) term by term will eliminate the x- term
(2x - 2x) + (2y - 5y) = 6 - (- 3), that is
- 3y = 9 ( divide both sides by - 3 )
y = - 3
Substitute y = - 3 in either of the 2 equations and solve for x
Substituting y = - 3 in (1)
2x + 5(- 3) = - 3
2x - 15 = - 3 ( add 15 to both sides )
2x = 12 ( divide both sides by 2 )
x = 6
Solution is (6, - 3 )
