Step-by-step explanation:
In Exercise B, the complement of an angle is 90° - ∠X
4. 90° - 45° = 45°
5. 90° - 20° = 70°
6. 90° - 30° = 60°
7. 90° - 55° = 35°
8. 90° - 75° = 15°
9. 90° - 80° = 10°
In Exercise C, the supplement of an angle is 180° - ∠X
10. 180° - 20° = 160°
11. 180° - 105° = 75°
12. 180° - 90° = 90°
13. 180° - 150° = 30°
14. 180° - 135° = 45°
15. 180° - 120° = 60°
Answer:
8, 9
Step-by-step explanation:
The answer is 8, and 9
72 = x*(x+1)
Lets factor out 72
1 x 72
2 x 36
3 x 24
4 x 18
....
8 x 9
8 and 9 are consecutive
This isn’t English. Again how am I supposed to answer?
