What are the diagonals of a rhombus

Every rhombus has two diagonals connecting pairs of opposite vertices, and two pairs of parallel sides. ... The two diagonals of a rhombus are perpendicular; that is, a rhombus is an orthodiagonal quadrilateral. Its diagonals bisect opposite angles.

1.- x < 10

2.- x ≤ -4

3.- x > 4

Step-by-step explanation:

in this type of graph when you have an empty circle it means that that number is not included in the interval, and when you have a filled circle it means that the number is included in the interval.

1.- in the first graph you have an the values less than 10, not including the 10. This is represented by the following inequality

x < 10

2.- in the second graph we have that the interval includes values less than -4, this time including the -4, so the inequality is:

x ≤ -4

3.- in the last graph the interval includes values greater than 4, without including the number 4, so the inequality is:

x > 4
