Answer:

66

Step-by-step explanation:

Angle 2 and 4 are supplementary, so if angle 4 is 123, then 180-123=57.

So angle 2 is 57.

Then, if angle 2 and 3 are 57 and we know that all angles of a triangle have to add up to 180, then:

                             57+57+angle 1=180

                                114+ angle 1=180

                                        angle 1= 66
