Answer 1

C. (3x +12) + x = 180°

Explanation:

(3z+12)° is obtuse. x° is acute.

Both are supplementary angles that are linear pair that add up to 180°

(3x + 12)° + x° = 180°

4x + 12 = 180°

4x = 168°

x = 42°

Plug x into (3x + 12)°

3*42° + 12

126 + 12

138°

Answer 2

So the whole thing is 180, we already have 3x+12, it's C.
Because A would be 3x +180 (1803x) +something else which would bring it over 180.

Explanation:

C is the answer because 180 is the toal and it isn't going over 180 right away.
