Answer:

x = 21

Step-by-step explanation:

The 2 angles form a straight angle and are supplementary, thus

7x + 9 + 2x - 18 = 180, that is

9x - 9 = 180 ( add 9 to both sides )

9x = 189 ( divide both sides by 9 )

x = 21

Rhombus J K L M is shown. The length of J K is 2 x + 4 and the length of J M is 3 x.
Dominik [7]

Answer:

12 units

Step-by-step explanation:

Properties of Rhombus:

1. length of all sides are equal.

2. Diagonals bisect each other at right angles

As the length of all sides are equal,

JM = JK

3x = 2x + 4

Subtract 2x from both sides,

3x - 2x = 4

       x = 4

JM = 3*4 = 12 units
