<h3><u>Solution</u> :</h3>
9. if mA = 48° , then
- mB = 90° - 48° = 42°
- mC = 180° - 42° = 138°
10. if mB = 83°, then
- mA = 90° - 83° = 7°
- mC = 180° - 83° = 97°
11. if mC = 127°, then
- mB = 180° - 127° = 53°
- mA = 90° - 53° = 37°
12. if mA = 25°, then
- mB = 90° - 25° = 65°
- mC = 180° - 65° = 115°
