Answer 1

let us consider the two unknown angles to be x and y. Suppose x>y

we know,
                         x+y=180                    -(1)
given that
                         x-y=102                      -(2)
adding equations (1) and (2)
                        x+y+x-y=180+102
                        2x         =282
                        x=282/2=141
therefore
y=180-141=39
the two angles are 141 degree and 39 degree
