Answer:

x = 210 and 330 degrees  where  0 =< x <= 360.

Step-by-step explanation:

The angles whose sine is -1/2 are 210 and 330 degrees for angles between 0 and 360 degrees.

The general results are 210 +/- 360  and 330 +/- 360 degrees.

liq [111]

Answer:

What is an equation of the line that passes through the point (-2 1) and is parallel to the line whose equation is 4x-2y=8 ?
monitta
4x-2y=8 ==> y=2x-4 (to better show you what I mean) 

2 lines are parallel if they have the same slope (m the coefficient of x).

So y=mx + b // y =2x-4 means m=2 & y=mx + b, becomes y=2x + b.
Moreover they are telling us that this function passes by (-2,1), where -2 represents x & 1, represents y. To calculate b , replace x & y by their values:
y=2x+b ==> 1 = 2(- 2) + b==> 1 = -4 + b ==> b= 5. Finally the equation is
y=-2x+5
