  • m and 125º are supplementary angles:

    m + 125º = 180º

    m = 180º – 125º

    m = 5  <———    this is the answer.


    I hope this helps. =)

  • Answer:

    m = 55

    Step-by-step explanation:

    125 and m are adjacent angles  (supplementary).

    remember supplementary angles add up to 180

    so sub 180 and 125 to get the angle measure of m
