Suppose that P is the point on the unit circle obtained by rotating the initial ray counterclockwise through 330 degrees. Find t
Flauer [41]

Answer:

Reference angle will be 30°

sin(330°) will be equal to \frac{-1}{2}

cos(330°) will be equal to 0.866

Step-by-step explanation:

We have given angle is 330°

As the angle 330^{\circ} is in forth quadrant

We know that in forth quadrant the reference angle is given by

Reference angle =360-angle

As the angle is 330°

So the reference angle will be =360-330=30^{\circ}

Now we have to find the value of

sin(330°) =sin(2\pi -30)=-sin(30)=\frac{-1}{2}

And now cos(330^{\circ})=cos(2\pi -30)=cos30=0.866

What is an equation of the line that passes through the point (−1,6) and is parallel to the line 2x+y=9
Alex73 [517]

Answer:

2x + y = 4

Step-by-step explanation:

2x + y = 9 => y = -2x + 9

Parallel lines have the same slope so m = -2

Given (-1,6)

y = mx + b

6 = -2(-1) + b

6 = 2 + b

b = 4

so y = -2x + 4 or 2x + y = 4
