<span>The reference angle is closest to the x-axis.
I will assume the above is 7pi/6. That would be a reference angle of pi/6, and the sin in the 3rd quadrant is negative, so the sin theta = - 0.5</span>
First factor the numerator
b^2-6b+8/b-4 * b+8/b-2
u will get
(b-2)(b-4)/(b-4)*(b-2)*b+8
those will cancel out each other will left only
b+8<span />
The worst case is when you pull 4 out and have 4 different colors. the 5th sock MUST match one of these. 5 is the answer
Answer:
x= 50°
Hope it helps!
Step-by-step explanation:
The sum of the exterior angles of a polygon is always 360°
So, x+40+x+20+2x+2x = 360
6x + 60= 360
6x = 360-60 = 300
6x= 300
x= 300/6
= 50

but this would have to be simplified also
