Answer:
That all you would need to figure anything out. First thing you need to remember is that every triangle is 180 degrees total. Let's say one angle of a triangle 50 and the other is 35. If you were to add 5o and 35 together, you would get 85. Then I would do 180 - 85 and that would give you the remaining and missing angle. Hope this helps<3 !!
