A70° angle, a 30° angle, an 80° angle how many triangles can be made with the angle measures shown here? a. no triangle b. a unique triangle c. more than one triangle d. the answer cannot be determined

The sum of all angles in any given triangle add up to 180 degrees;
In this case the sum  is 70+30+80 
Which gives, 180 degrees,
Thus a triangle can be formed; but since we are not given any measurements of the edges , more than one triangle can be formed depending on the length of the edges used.
Therefore the answer is C. more than one triangle.
