I need help on number 3 please!!

Answer:
Yes the two triangles are similar
Step-by-step explanation:
For two triangles to be similar, all three of the angles must be the same, side lengths are irrelevant. So triangle 1 has a 50 and 25 degree angle so to find the third you subtract them from 180. This leaves you with 105. So triangle 1 is a 50-25-105 triangle. Now make sure that triangle 2 is also a 50-25-105 triangle. Triangle two has a 50 and 105 degree angle. Subtract those from 180 and you get 25. So both triangles have the same angle measurements making them similar.
