To find the missing angles, we use the rule for complementary angles: two angles are complementary if they add up to 90 degrees.

So, for each problem, we subtract the given angle from 90 to find the missing one.

---

1) Given: 65°
Missing angle $ n = 90 - 65 = 25 $

2) Given: 28°
Missing angle $ j = 90 - 28 = 62 $

3) Given: 57°
Missing angle $ a = 90 - 57 = 33 $

4) Given: 15°
Missing angle $ e = 90 - 15 = 75 $

5) Given: 68°
Missing angle $ c = 90 - 68 = 22 $

6) Given: 41°
Missing angle $ h = 90 - 41 = 49 $

---

All calculations checked and correct.

Final Answer:
1) n = 25
2) j = 62
3) a = 33
4) e = 75
5) c = 22
6) h = 49
