Answer:
It is a factor.
Step-by-step explanation:
its definitely a factor
rule: put (x-2)=0
so x = 2
now put this 2 in the equation as x

which equals to 0, as a result its a factor
you can check the sum in the calculator by yourself
hope it helps.
i think it 30 but I could be wrong

Answer:
a =
and b =
Step-by-step explanation:
As we know, the radius of the unit circle is 1 unit (it is the hypotenuse in the right triangle, the blue line)
We use trigonometric formulas to find out a and b
- Sin(45) = opposite side / hypotenuse
<=> Sin(45) = b / 1
<=> b= Sin(45)*1 =
- Cos(45) = adjacent side / hypotenuse
<=> Cos(45) = a / 1
<=> a = Cos(45)*1 = 
So: a =
and b =
