Question

5.

Answer 1

Answer:

C) 4/5

Step-by-step explanation:

pi/4 = 0.7853981634

$\frac{\sqrt{3} }{2}$ = 0.8660254038

3/4 = 0.75. It's less than pi/4, so not correct

9/10 = 0.9. It's more than 0.866, so not correct

4/5 = 0.8. It's right for both condition

8/9 = 0.888. It's more than 0.866, so not correct.
