Answer:
EF is 4 units.
Step-by-step explanation:
It is given that the two triangles 
are congruent to each other i.e.
Coordinates are given as:
A(-1,1)
B(2,4)
C(3,1)
As per the property of congruence, all the corresponding sides and angles of the two triangles are equal to each other.
i.e. AB = ED
BC = DF
AC = EF
We are given with the coordinates of points A, B and C here from which we can easily calculate the side AC using the distance formula.
Where 
are the coordinates of the two points whose distance is to be calculated.
So,
Hence, <em>AC = EF = 4 units</em>
Hello, you are solving formulas in this case, heres a good way of doing these problems: :)
We know that that 10 people shake hands, so each person shakes 9 hands. The first person shakes 9 hands, the second person shakes 8 hands, the third person shakes 7 hands, and so on. That would give you the answer, however in the case of bigger numbers, this technique is not the best, in fact the best is by doing the following.
Each handshake consists of two people shaking hands. How many ways can <span>you choose those two people if there are 10 people in the group? You
can choose any one of 10 people for the first person involved in the
handshake; then for each of those 10 choices, you have 9 choices for
the second person. So you have 10*9 = 90 ways of choosing the two
people for the handshake.
But wait a minute. Person A shaking hands with person B is the same as
person B shaking hands with person A; this means that in counting the 90 handshakes you have actually counted each one twice, so the
actual number of handshakes is half of 90, or 45.
I hope i helped, and your final answer is 45
Thank you,

A = 45
b = 75
c = 37
d = 137
a-
whenever the angle is shaped like that they are equal i forgot the actual property name though
b-
and the known angles up (so 45 and 60) then subtract 105 from 180 to get 75 which is the answer
c-
add the known angles then subtract from 180 (so add 75 and 68) then u should get 37
d-
add all known angles then subtract from 180 (so add 37 and 100) you should get 43
then ur gonna subtract 43 from 180 to get the answer which is 137
