Answer:

5.656 units

Step-by-step explanation:

Data provided:

coordinates of the point 1 as (−1,−13)

and,

coordinates of the point 2 as (3,−9)

Now,

The distance between the two points whose coordinates is given is calculated using the formula

distance = \sqrt{(x_2-x_1)^2+(y_2-y_1)^2}

on substituting the respective values, we get

distance = \sqrt{(3-(-1))^2+(-9-(-13))^2}

or

distance = \sqrt{(4)^2+(4)^2}

or

distance = \sqrt{16+16}

or

distance = √32

or

distance = 5.656 units

Given JM=27, ml=16, jl=46, nk=15, KLM= 48, JkM=78, MJL=22, find each missing value.
Llana [10]

Answer:

KL = 27

JK = 16

MK = 30

NL = 23

m∠JKL = 132°

m∠KLJ = 22°

m∠KMJ = 54°

m∠KJL = 26°

Step-by-step explanation:

The given parameters of the quadrilateral JKLM are;

JM = 27, ML = 16, JL = 46, NK = 15, KLM = 48, JKM = 78, MJL = 22

Taking the sides as parallel, we have that quadrilateral JKLM is a parallelogram

Therefore;

KL = JM = 27

JK = ML = 16

m∠KLJ = m∠MJL = 22°

MN = NK = 15

MK = MN + NK = 15 + 15 = 30

NL = JL/2 = 46/2 = 23

m∠KJM = m∠KLM = 48°

m∠KJL = m∠KLM - m∠MJL = 48° - 22° = 26°

m∠KML = m∠JKM = 78°

m∠MKL = 180° - m∠KML - m∠KLM = 180° - 78° - 48° = 54°

m∠MKL = 54°

m∠JKL = m∠JKM + m∠MKL = 78° + 54° = 132°

m∠KMJ = m∠MKL = 54°
