Sagot :

99 degrees

180 - 123 = 57
180 - 57 - 42 = 81
180 - 81 = 99
Because the angle that is opposite 123 degrees it will equal 180. You do 180-123 which is 57 then the angle on the opposite side (angle x) the angle which is on the other side of it will be 57 degrees. To find the size of angle x you would have to do 180- 57 which is 123 degrees

Answer: 123 degrees
