Answer:
Given statement is TRUE.
Step-by-step explanation:
Given that line segment JK and LM are parallel. From picture we see that LK is transversal line.
We know that corresponding angles formed by transversal line are congruent.
Hence ∠JKL = ∠ MLK ...(i)
Now consider triangles JKL and MLK
JK = LM {Given}
∠JKL = ∠ MLK { Using (i) }
KL = KL {common sides}
Hence by SAS property of congruency of triangles, ΔJKL and ΔMLK are congruent.
Hence given statement is TRUE.

Nollie told the police that Annaliese was a Jew
Step-by-step explanation:
C(F) is the degrees Celsius given the degrees Fahrenheit.<span />
Ropes are 9.63 meters ans 8.178 meters.
<u>Step-by-step explanation:</u>
Step 1 :
List all the given things
Distance between people holding ropes = 40 =(40*0.3048) meters = 12.192 meters
Angle between two ropes = 86 degrees
Angle of elevation of one rope = 42 degrees
Step 2 :
Two angles of triangle are already given so third angle can be calculated as -
Third angle = 180 - ( 86 + 42 ) = 52 degrees
Step 3 :
As we know all three angles we will apply sine rule now, which is
Step 4 :
By putting values, we have
Step 5 : Calculating a and b
,
Step 6 :
By putting values of all sine and calculating we get,
a = 9.63 meters and b = 8.178 meters
255 different groups of 4 paints can be selected out of the 20 paintings.
<h3>How many groups of four paintings can be chosen?</h3>
If we have a set of N elements, the number of groups of different sets of K elements that we can make out of these N is given by:
C(N, K) = N!/(K!*(N - K)!)
In this case we have a total of 20 paintings, and the curator wants to select 4, then we have:
N = 20
K = 4
The number of different combinations of 4 paintings is given by
C(20, 4) = 20!/(4!*16!) = (20*19*18*17)/(4*3*2*1) = 255
This means that 255 different groups of 4 paints can be selected out of the 20 paintings.
