Answer:

  A.  40° and 40°

Step-by-step explanation:

The triangle cannot have two angles measuring 100°, so the remaining two angles must be equal to each other. This eliminates choices B and D.

The sum of angles in the triangle must be 180°. This eliminates choice C.

The two other angles must both be (180° -100°)/2 = 40°.
