Answer:
In option a, w < 10
in option b, w = 10 and 2(20) + 2(10) = 40 + 20 = 60 < 150
in option c, w > 10 but 2(60) + 2(20) = 120 + 40 = 160 > 150
In option d, w > 10 but 2(55) + 2(30) = 110 + 60 = 170 > 150
Therefore the corect answer is option b.

Answer:
 a =  and b =
 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 =
 and b =
