Use the sin identity to find that side. Sin(30) = a/12...12 sin(30) = a, and a = 6
I guess positive bcuz - -=+

what's your question though?
Answer:
omg i can't do that
Step-by-step explanation:
First subtract the number that did, to find the number that didn't.
1300 - 520 = 780 customers did not order coffee.
Now divide the number who didn't order coffee by total number of customers:
780 / 1300 = 0.6
Multiply by 100 to get the percent:
0.6 x 100 = 60% did not order coffee.
