and 
, otherwise known as 
. Therefore, the correct answers are I and III. You can see the unit circle below, where the y coordinates of the above angles show .
Answer: the number is 369
Step-by-step explanation:
Let the missing number be y
8/9 × y = 328
8/9y = 328
Divide both sides by 8/9
y = 328 ÷ 8/9
y = 328 × 9/8 (multiply the two numerators: 328 x 9= 2952
Multiply the denominator by 1: 8 x 1= 8
Therefore y = 2952/8
y = 369
