Hope this helps :)
pls mark as brainliest :))
1. C. Concave pentagon
2. A. 1620°
b/c (11 - 2) × 180 = 1620
3. B. 165°
b/c (24 - 2) × 180 ÷ 24 = 165
4. A. 160°
b/c (18 - 2) × 180 ÷ 18 = 160
9. 31 + 5 = 36
10. 16 - 4 = 12
12. 9
13. 44 + 34 = 78
14. 101 - 1 = 100
15. -539 ???
16. 15 ??
17. |-435| = 435
