4
Step-by-step explanation:
Answer:
Below
Step-by-step explanation:
Let's prove that cos^2(O) = 1+ cos(2O)/2
We khow that cos(2O) = 2 cos^2-1
● cos(2O) = 2 cos^2-1
Add one to both sides:
● cos(2O) +1 = 2 cos^2-1+1
● cos(2O) +1 = 2 cos ^2
Divide both sides by 2
● [cos(2O)+1]/2 = cos^2
7 + 5 + 2 = 14 because seven plus five is twelve, twelve plus two is fourteen.
