Answer:
d) x=43
Explanation:
A rule for this problem can be as followed:
All exterior angles of a quadrilateral sum up to 360 degrees.
So, let's write an equation:
3x+2x+(x+2)+100=360
subtract 100 from both sides
3x+2x+(x+2)=260
combine like terms
6x+2=260
subtract 2 from both sides
6x=258
divide both sides by 6
x=43
So, d is the correct option.
Hope this helps! :)
