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

Hi zee-f;

Now solve for c.

(m+2m)+c=180

m+2m=3m

3m+c=180

-3m -3m

c= 180-3m

so the answer would be F

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!

Writing "pretty" math (two dimensional) is easier to read and grasp than LaTex (one dimensional).

LaTex is like painting on many strips of paper and then stacking them to see what picture they make.
