A 70° 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.
