Answer:
8
Step-by-step explanation:
The formula to calculate the sum of interior angles of polygon is (n - 2)180
Where n represents number of sides
(n-2)180 = 1080 ------ Divide through by 180
(n-2)180/180 = 1080/180
n-2 = 6
n = 6+2
n = 8
Step-by-step explanation:
=9x+2(2x+3)
=9x+4x+6
=13x+6 I hope so,
23(x)-85
Substitute 12 for x
23(12)-85
276-85
