Answer:

Answer choices A, C, and D.

Step-by-step explanation:

If you assume that the 70 degrees is one of the base angles, then the other base angle is also 70 and the third angle is 40 degrees (thus answers C and D). However, if it is the top angle, the other two angles must both be 55 degrees (thus answer A). Hope this helps, and PM me with questions!
