Hey!
First lemme say you what is the meaning of complementary angle.
The angles when added gives 90° are called complementary angles.
First one is a complementary angle as when added both gives us 90°.[25°+65°]
Second one isn't complementary angle as when added wont give 90°.
Third one is complementary as 45°+45° = 90°.
And the last 4th one isn't complementary as when added wont give us 90°.
Hope this helped you :D
