0. Imagine a right triangle with A = 30 degrees, b = 17, what would a be? It would be 17 tan 30 which is about 9.81. This is the length of the perpendicular dropped from B to side b, which means if you draw a circle centered at B with radius 9, it would not intersect side b. So no such triangle can be formed.
All triangles are 180 degrees.
As many as you like because any triangle that has a 90 degree angle is always a right angle triangle.
Infinitely many.
Infinitely many. Having found one triangle, you can find infinitely many similar triangles.
60 degrees... since triangles have to have 180 degrees in total, and all sides have to be equal.
There is 180 degrees in all triangles
As many as you like but they will all be scalene triangles formed by the given angles that add up to 180 degrees
170 degrees.
all triangles are 180 degrees altogether
All triangles are 180 degrees.

Triangles are always 180º when the angles are added up. There is no inside angle verses and outside angle.
To find interior angle measurements, you must divide the shape into triangles by drawing diagonal lines. The diagonal lines draw triangles, and the interior angle measure of triangles are always 180 degrees. The sum of interior angles of an octagon is 1080 degrees. How ever many triangles you have, multiply it by 180. See octagons in the link for more help,
All triangles have 3 interior angles that add up to 180 degrees.
