Greetings from Brasil...

Just 2 equal angles are enough for the triangles to be similar .... The second triangle has the same angles as the first.

We know that the sum of the internal angles of a triangle is 180, so for the second triangle:

84,6 + 65 + X = 180

X = 180 - 84,6 - 65

X = 30,4   →   same angle as the largest triangle

So we have AA~ similarity
