Step-by-step explanation:

144

Step-by-step explanation:

to find the missing angle in side of the triangle we subtract 111 and 33 from 180

180-111-33=36

so the angle inside of the triangle equals 36 to find the one on the outside of the triangle we subtract 36 from 180

180-36 which equals 144 so 1=144
