All exterior angles will add up to equal 360 for all polygons

anonymous · Answer

ok so  what does that mean for the problem @Fuzure

anonymous · Answer

This means that all of the equations you were given for the angles will all add up to 360
So add up all the equations and set it equal to 360. Then solve for x

ok 1 minute

anonymous · Answer

@Fuzure  i got 7x=319  so x=11.814

anonymous · Answer

I got 27x + 90 = 360

anonymous · Answer

oh i think i added wrong

anonymous · Answer

did you remember to add the 49 degrees at angle c?

anonymous · Answer

oh no i didnt

anonymous · Answer

oh X=10

anonymous · Answer

yes, so now we can solve for angle a

anonymous · Answer

plug back x into 6x-3

anonymous · Answer
