Hi zee-f!

In all these problems you are to find the supplement to the sum of the two given angles I assume.
That would be in all these cases 180 - (sum of the two angles).
Eg. 16)  180-(68+86) = 180-154 = 26.
      20)  180-(m+2m) = 180-3m.

Be blessed! smile

(m+2m)+c=180
m+2m=3m

3m+c=180
-3m        -3m

c= 180-3m

so the answer would be F

Hi zee-f;



Now solve for c.

I got all of them correct but 20 neutral so wouldn't be m+2m=180
