Answer:
360/12 = 30 degrees
Step-by-step explanation:
To find any exterior angle, you need to divide 360 degrees by the total number of sides from the polygon.
Since the polygon in question is a dodecagon (with 12 sides), all you need to do is divide 360 degrees by 12, thus, the size of the exterior angle is 30.
Answer:
x = 1
Step-by-step explanation:
Given
5(2x - 8) + 15 = - 15 ( subtract 15 from both sides )
5(2x - 8) = - 30 ( divide both sides by 5 )
2x - 8 = - 6 ( add 8 to both sides )
2x = 2 ( divide both sides by 2 )
x = 1
