Ответ:
It would be triangles A & C
Step-by-step explanation:
This is because all of the angles within triangle add up to 180, with this, you can do the following to find the missing sides:
Tri A:
180-110-30 = 40
Tri B:
180-45-30 = 105
Tri C:
180-110-40 = 30
When you do this, look at the angles of the triangles. You see that Triangle A with the angles 110, 30, and 40 all match with those seen in Triangle C.
Therefore, the two triangles are congruent.
