The value of x from the given circle is 12
<h3>Circle theorem</h3>
Angle at the vertex of the circle is half the angle at its intercepted arc.
From the given circle;
The measure of <DEF = 80/2 = 4x -8
Equate both angles
4x - 8 = 80/2
Add 8 to both sides
4x - 8 + 8 = 40 + 8
4x = 48
x =12
Hence the value of x from the given circle is 12

Answer:
9 sides
Step-by-step explanation:
exterior angle + interior angle = 180° , so
exterior angle + 140° = 180° ( subtract 140° from both sides )
exterior angle = 40°
The sum of the exterior angles of a polygon = 360°
Dividing sum by the measure of 1 exterior angles gives number of sides
number of sides =
= 9
