[tex]180-152= 28\\28+115=143\\180-143=37\\m<1=37[/tex]

Answer:

Step-by-step explanation:

6a. inside the triangle:

      x + 62 + 67 = 180

       x + 129 = 180

       x = 51

For <1: m<1 + 51 = 180

           m<1  = 129

6b. for next to the exterior:

       x + 152 = 180

       x = 28

Inside the triangle:

 m<1 = m<1 + 28 + 115 = 180

           m<1 + 143 = 180

           m<1 = 37
