Answer 1

Answer:

109

Step-by-step explanation:

Supplement of angle = 180 degree

Measures of angle = (55* + 3a) + (15* - 2a) = 180*

                                     58a + 13a                    = 180*

                                     71a                               = 180*

   Now, transpose 71 to right side and subtract with 180*.
