leaves you with 15 on the right side
you then divide by negative 2
since you divide by a negative you have to switch the sign
Answer: see proof below
<u>Step-by-step explanation:</u>
Given: cos 330 = 
Use the Double-Angle Identity: cos 2A = 2 cos² A - 1

Proof LHS → RHS:
LHS cos 165
Double-Angle: cos (2 · 165) = 2 cos² 165 - 1
⇒ cos 330 = 2 cos² 165 - 1
⇒ 2 cos² 165 = cos 330 + 1
Given: 

Divide by 2: 

Square root: 
Scratchwork: 

Since cos 165 is in the 2nd Quadrant, the sign is NEGATIVE

LHS = RHS 
Hello!
If Barbara mixes 54 ounces of granola and 36 ounces of raisins, the overall mixture will equal 90 ounces. In order to find the amount of servings that Barbara makes, we must divide the total number by the other number given - 6.
Because Barbara wants to divide the mixture into 6 ounce servings, we will divide 90 by 6.
90/6=15
The answer to your question is "Barbara made 15 6-ounce servings."
I hope this helps you! Have a great day!
