please help me!!?

In the large triangle:
The third angle = 180° - (88° + 30°) = 62°

Hence, the two triangles have at least two angles equal.
They are similar and the reason is AA.

The answer: A. AA

A.  AA because the third angle (computed by subtracting the measure of each from 180 degrees) in each triangle is the same as one already listed in the opposing triangle.

180-88-30=62
A  two angles are the same so tri's are similar.

Angle A = Angle B = 88

Triangle BIG  ≈ Triangle SMALL

By Angle similarity The answer is A
