Solve dis. its a photo. and please answer correctly

See below because you don't specify if they are complementary or supplementary angles

Step-by-step explanation:

Solution if supplementary:

12x+12+15+3x+18=180

15x+45=180

15x=135

x=9

m<A=12(9)+12=108+12=120 degrees

m<C=3(9)+18=45 degrees

Solution if complementary:

12x+12+15+3x+18=90

15x+45=90

15x=45

x=3

m<A=12(3)+12=48 degrees

m<C=3(3)+18=27 degrees
