Answer:
x=±8
Step-by-step explanation:
You add 11 on both sides
x^2=53+11
x^2 = 64 so
x=8 or x=-8
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
Hi!
2.06m + 6.13 = 17.78
First subtract 6.13 from both sides
2.06m + 6.13 - 6.13 = 17.78 - 6.13
2.06m = 11.65
Divide by 2.06 on both sides
2.06m/2.06 = 11.65/2.06
m = 5.7
