Question

Someone please help !! :)

geometry : angles of polygons & parallelograms (unit 7)

Q : find the value of x

Answer 1

x = 13

Explanation:

the sum of the exterior angles of a polygon is 360°

sum the 6 exterior angles and equate to 360

3x + 6 + 41 + 6x - 5 + 4x + 7 + 62 + 7x - 11 = 360

20x + 100 = 360 ( subtract 100 from both sides )

20x = 260 ( divide both sides by 20 )

x = 13
