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: 63°
Missing angle $ c = 90 - 63 = 27^\circ $

2) Given: 18°
Missing angle $ r = 90 - 18 = 72^\circ $

3) Given: 46°
Missing angle $ x = 90 - 46 = 44^\circ $

4) Given: 52°
Missing angle $ m = 90 - 52 = 38^\circ $

5) Given: 76°
Missing angle $ p = 90 - 76 = 14^\circ $

6) Given: 35°
Missing angle $ b = 90 - 35 = 55^\circ $

---

All calculations checked and correct.

Final Answer:
1) c = 27°
2) r = 72°
3) x = 44°
4) m = 38°
5) p = 14°
6) b = 55°
