Answer:
1) B, C, and D
2) plane BFD
Step-by-step explanation:
1) Collinear points are points on the same line. There are two lines shown. One of them shows points A, C, and E on it. The other line shows points B, D, and D on it. The latter set of points is listed among the answer choices.

2) A plane can be named by three points in the plane that are not on the same line. The points shown as being in the plane are B, C, D, F, with points B, C, and D being on the same line (see question 1). So, the plane can be named with point F and any two of B, C, and D. Plane BFD is an appropriate name.
The sum of all three angles of a triangle must equal to 180°.
6x + 2x + 2x = 180
10x = 180
x = 18
2 * 18 = 36.
Your answer should be 36°.
Answer:
1 hr 15 mins
Step-by-step explanation:
Simplify the question:2ab(3)(-7)
2ab(-21
The point (-11,34) has the coordinates x = -11 and y = 34
The point (47,0) has the coordinates x = 47 and y = 0
Let's focus on just the x coordinates of each point for now. Those values are -11 and 47. Add them up to get -11+47 = 36. Then divide by two to end up with 36/2 = 18
The x coordinate of the midpoint is x = 18
Repeat those steps for the y coordinates. First add them up: 34+0 = 34. Then divide by two: 34/2 = 17
The y coordinate of the midpoint is y = 17
<h3>Therefore the midpoint is located at (x,y) = (18,17)</h3>
--------------------------
side note:
If you want, you can use the formulas
xm = (x1+x2)/2
ym = (y1+y2)/2
where (x1,y1) and (x2,y1) are the two endpoints and (xm, ym) is the midpoint. Though this method may be a bit confusing.
