A pair of complementary angles is
- 42° 16', 47° 34'
- 34° 10', 55° 50'
- 53° 27', 29° 33'
- 19° 26', 70° 36'
Answer
Evaluating all options:
Sum of minutes: 16' + 34' = 50'
Sum of degrees: 42° + 47° = 89°
Total: 89° 50'
Sum of minutes: 10' + 50' = 60' = 1°
Sum of degrees: 34° + 55° = 89°
Total: 89° + 1° = 90°
Sum of minutes: 27' + 33' = 60' = 1°
Sum of degrees: 53° + 29° = 82°
Total: 82° + 1° = 83°
Sum of minutes: 26' + 36' = 62' = 1° 2'
Sum of degrees: 19° + 70° = 89°
Total: 89° + 1° 2' = 90° 2'
Among all these, second option gave the result 90°.
Hence, option 2 is the correct option.
