The measure of ∠DAB equals 105º. The measure of ∠ACB equals 35º.

What is m∠ABC?

1) We know that <DAB and <BAC are supplementary angles according to the exterior angle theorem, so we set up the following equation and solve:

105+x=180

x=75

2) Since we have the angles for <BAC and <ABC and a triangle has its total angles added up to 180, we can set up an equation to find <ABC and solve:

75+35+x=180

110+x=180

x=70

So the m<ABC is 70 degrees.

Hope this helped! Let me know if you need me to clarify anything.
