Hitman42 [59]

Answer:

The answer to your question is:

x = 1

y = 1

z = 0

Step-by-step explanation:

                                -2x + 2y + 3z = 0             (1)

                                -2x - y + z = -3                  (2)

                                 2x + 3y + 3z = 5              (3)

Solve (1) and (2)  

Multiply 2 by 2

                                 -2x + 2y + 3z = 0

                                 -4x -2y   + 2z = -6

                                -6x          + 5 z = -6        (4)

Solve (2) and (3)

Multiply 2 by 3

                               -6x - 3y + 3z = -9

                                2x + 3y + 3z = 5

                               -4x         + 6z = -4           (5)

Solve (4) and (5)

Multiply (4) by 2 and (5) by -3

                           -12x    + 10 z = -12

                            12x    -  18z   = 12

                                         -6z = 0

                                          z = 0

Then

            -4x + 6(0) = -4

           -4x = -4

            x = -4/-4

            x = 1

Finally

                 -2(1) - y + (0) = -3      

                -2 - y = -3

                 -y = -3 + 2

                 y = 1

Please help me find the value of each variable in the parallelogram
seropon [69]

Answer:

K=10 H=65

Step-by-step explanation:

To work out K, you need to know that opposite angles are the same, so 5k is the same as 50, 50÷5= 10, so k=10

To work out H, you know that opposite angles are the same so 2h is the same as 130, 130÷2=65 so h=65
