X = 180 - 58 - y
Y = 180- 126= 54
X= 180 - 58 - 54
X= 180- 112= 68 degrees
Answer:
Find the distance between (-1, 1) and (3, 4).
This problem is solved simply by plugging our x- and y-values into the distance formula:
D=(3−(−1))2+(4−1)2−−−−−−−−−−−−−−−−−−√=
=16+9−−−−−√=25−−√=5
Sometimes you need to find the point that is exactly between two other points. This middle point is called the "midpoint". By definition, a midpoint of a line segment is the point on that line segment that divides the segment in two congruent segments.
If the end points of a line segment is (x1, y1) and (x2, y2) then the midpoint of the line segment has the coordinates:
(x1+x22,y1+y22)
Answer:
vertex form
Step-by-step explanation:
y= -3(x-5)^2+7
This equation is written in vertex form
y = a(x-h)^2 +k
The vertex is (h,k)
Answer:
Step-by-step explanation:
The computation is shown below:
The numbers of possible results at the time when we drawing in two tries is 9
i.e. shown below:
11, 12, 13, 21, 22, 23, 31, 32, 33
Now the probability is
Divide both sides by 2.
