    Is \(\sf\Large \angle BCD + \angle ABC\) supplementary or complementary?

    correct, so that means it adds upto 180

    \(\sf\Large \angle BCD + \angle ABC=180\) Now substitute the value that was given for \(\sf\angle ABC\) into it and solve for angle BCD

    now in a quadrilateral, the angles all add up to 360 degrees

    so first tell me what 127 + 127 =

    They gave you \(\sf\angle ABC = 127\)

    360 - 254 = ?

    106.

    106/2 = ?

  22. Mehek14

    so 106 degrees is the the total of the other 2 angles |dw:1434925346564:dw|

    53..?

    now you just need to find the measure of 1 angle so you divide 106 by 2

    yes so <BCD = 53
