What does mABC =

Answer 1

Answer:130 degrees

Explanation:

The problem gives you that m<ABD= 100 degrees, and m<DBC= 30 degrees.

m<ABC is a larger, combined angle of ABD and DBC, which means that it should equal to 130 degrees.

Answer 2

130, add the two measures together. So that is 100 + 30 which is 30. For future problems, make sure to look at the specific angles and create equations based on those.
Ex. ABD + DBC = ABC
and then plug in the values. Hope this helps!
