Answer: A and C

Explanation:

angles in a triangle add up to 180

180 - 30 = 150

other two angles must add up to 150 and two of the angles have to be the same.

Since one is already 30, one of the others have to also be 30 or both of the others have to be the same.

A and C both add up to 150 and both of them have one angle repeating
