Answer:
10 sides.
Step-by-step explanation:
Two same interior angles + 72 degrees = 360.
Thus, the interior angle of the polygon is .
The formula to find the interior angle of a polygon is
Multiply both sides by n:
Expand:
Add 360 to both sides:
Subtract 144n from both sides:
Divide both sides by 36:
Answer:
Step-by-step explanation:
7x + 14 = 6x + 30
x + 14 = 30
x = 16

Answer:
none
Step-by-step explanation:
No choice is correct.

None of the choices show 560 x 70. They show 560 + 70 and 560 - 70.
Answer: none
