<span>The reference angle is closest to the x-axis.
I will assume the above is 7pi/6. That would be a reference angle of pi/6, and the sin in the 3rd quadrant is negative, so the sin theta = - 0.5</span>
Answer:
Cost of dinner: $10.85
Money to add: $1.40
Step-by-step explanation:
1. Calculate the cost of the chicken and broccoli: 3(3.15)+1(1.40)=$10.85
2. Subtract Jared's money from the cost of dinner: $10.85-$9.45=$1.40
30/7 +30/7=60/7
60/7-22/7=38/7
59/7 -38/7=21/7
21/7 -19/7=2/7
