The first , second and fourth choices are correct.
Answer:
6. c = 5
7. b = 8
8. a = 0.75
9. b = 12
10. c = 0.5
11. c = 17
12. b = 1.34
13. a = 4.5
14. a = 1.2
15. c = 6.1
16. b = 15
17. c = 41
18. a = 7
19. c = 8.5
20. b = 4
Step-by-step explanation:
You need to use Pythagorean theorem. Put the number for a in a, b in b, and c in c. DON'T forget to square a, b, and c.
5) y=5 11/15
6) w=8.8
7) n= - 5 3/4
