685/5 = 137
137 doesn't factor at all, so your factors are 5 and 137.
The little lines inside the two angles mean they are the same.
The 3 inside angles of a triangle equal 180 degrees.
One angle is 146 , so the other two need to equal 180-146 = 34 total.
34/ 2 = 17
Both angle 1 and angle 2 are 17 degrees each.
I believe it would be 115 plus 56. subtract that from 180. i believe thisbis your answer
