Question

How many triangles can be constructed with angles measuring 120°, 40°, and 10°?

A. One

B. None

C. More than one

Answer 1

B.none because if you add up all the angles it doesn't equal 180 degrees

Answer 2

B. None.

The sum of the interior angles in a triangle always add up to 180°. In the question the angles add up to 170°, and therefore it is impossible to form a triangle with this interior angles.
