B) -1/2

C) {30, 150}

Step-by-step explanation:

Question 3)

We can see that the angle equals 210* which equals 7pi/6 (in radians)

The coordinates would be

Since the problem is asking for sinθ, we will use -1/2 (the y-coordinate)

So the answer is B) -1/2..

Question 4)

If the criteria of the answer is that it must be between 0 < θ < 360 and it must have a y-value of 1/2 in its coordinate (sinθ = 1/2), then we will choose angles that meet this criteria. When we look at the unit circle (see the attached) we can see that only the angles of 30* and 150* match this answer, so our answer is c.

step-by-step explanation :

we know that

the measurement of the outer angle is the semi-difference of the arcs which comprises

in this problem

m< xzy is the outer angle

substitute the values

the measure of angle xoy is equal to

> by central angle

substitute the value

"image"

step-by-step explanation:

in most of these problems, the notation is that the point with a "prime" is the image of the point without. that is, b' is the image of b.

here, there is no dilation or reflection. there is simply translation (with no direction shown). which figure you call the "preimage" and which one you call the "image" is up to you. as a matter of convention, the naming is as described above.
