Question

The following figures GUNS and RUNS are parallelograms . Find x and y . (Lengths are in cm)

Answer 1

Answer: (6, 9), (3, 13)

Step-by-step explanation:

Left picture:

opposite side of parallelograms are congruent (equal)

3x = 18                        3y - 1 = 26

÷3   ÷3                            +1   +1

  x = 6                          3y     = 27

                                  ÷3         ÷3

                                         y  = 9

**************************************************************************

Right picture:

diagonals of a parallelogram bisect each other so the left side and right sides of each diagonal are congruent

20 = y + 7

-7          -7  

13 = y

                           16 = x + y

                           16 = x + 13

                          -13       -13  

                            3  = x
