yeah it seems to be glitched -- but i somehow managed to see the image by clicking around LOL

the exterior angles of a polygon ALWAYS add up to $ 180^\circ $

since we know that, we can write the sum of all that we are given and write it all equal to $ 180^\circ $

$ \large[ (5x+4)+(4x+9)+(9x-6)+(4x+1)+(7x+4)=180 \large]^\circ $

$(5x+4+4x+9+9x-6+4x+1+7x+4=180)^\circ $

$ ( 29x+12=180)^\circ $

$ ( 29x=168)^\circ $

$ \boxed{ (x=\frac{168}{29}})^\circ $ which we can say just about $ \boxed{5.8^\circ} $

I think you're right.

Using the same solution idea as UsernameTooShort.

29x + 12 = 360

x = 12

oh lord i never noticed -- yes they indeed do add up to 360

at that moment i was working with triangles so thats why i was thinking of 180 LOL
