Answer:
can you edit and add the choices please? thank you!
Step-by-step explanation:
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.
N doesn’t have any lines of symmetry!
