To copy an angle using only a compass and a straightedge, begin by marking the vertex of the new angle. Then draw a ray from the vertex, which will be one of the legs of the new angle. What is the next step in the construction? A.
Set the compass width to the vertex of the angle, place the compass needle at any point on the leg of the new angle, and make an arc in the angle's interior.
B.
Set the compass to a sufficient width, place the compass needle on one leg of the original angle, and draw an arc on the other leg of the angle.
C.
Set the compass to a convenient width, place the compass needle on one of the legs of the original angle, and draw an arc on the leg of the new angle.
D.
Set the compass to a convenient width, and draw an arc that is centered at the vertex of the original angle and intersects both legs of the original angle.

step-by-step explanation:

"a" determine whether sage found the correct quotient. show your work

step-by-step explanation:

let's cover over the formula of the vertex:

y = a(x – h)^2 + k

in this formula, (h,k) are the vertex, always remember that the positive or negative value of the vertex is based on the sign it has.

for example, if the vertex is -3,-6 then both the x and y value would have the positive sign attached to it and if it were a positive x and y value, then a negative sign would be attached to it.

with that being said, for our problem the x value is a positive one so we are looking for a number with a negative sign next to it, in this case the first and second choice.

however, for the first answer choice it isn't quite part of the formula so we know that the answer choice correctly displays the x value.

to confirm, we can see if the -1 fits correctly with the second answer choice, and as mentioned above a negative number will have a positive sign attached to it. so, for our problem we can see that -1 has been changed to +1, so we can confirm that the second answer choice is correct.

hence, our final answer is y=(x - 1)^2 + 1
