Answer:
x = 13
Step-by-step explanation:
The sum of the exterior angles of a 4 sided polygon is 360
139+ 6x+9x+2x = 360
Combine like terms
139+17x=360
Subtract 139 from each side
17x = 360-139
17x = 221
Divide each side by 17
17x/17 = 221/17
x = 13
Answer:
It's 65.97
Step-by-step explanation:

Use distributive property on the right side:
y - 3 = 2x -8
Add 3 to both sides:
y = 2x -5
