Π/12 is half of π/6, which is 30 degree
tan(α/2)=(1-cosα)/sinα)
plug in the values: tan(π/12)=(1-cosπ/6)/sin(π/6)=(1-√3/2)/(1/2)=2-√3
Answer:
(2,3)
Step-by-step explanation:
The combined payment is 743.75.
The annual amount of insurance is 1560. Dividing this by 12 gives us the monthly amount paid:
1560/12 = 130.
The annual real estate taxes are 1890. Dividing this by 12 gives us the monthly amount paid:
1890/12 = 157.50
We add these to the monthly mortgage payment to find the total amount:
456.25+130+157.50 = 743.75
