9514 1404 393

  9. rhombus

  10. rhombus, rectangle, square

  11. rhombus

Step-by-step explanation:

9, 11. Angles are obviously not 90°, so each figure is a rhombus.

__

10. Line slopes are 1 or -1, so are perpendicular. Side lengths are all the diagonal of 6 squares, so 6√2.

The figure is a rhombus, rectangle, and square.

The answer is 8°

Step-by-step explanation:

2x + 62° = 5x + 38°

2x – 2x + 62° – 38° = 5x – 2x + 38° – 38°

24° = 3x

3x = 24°

3x/3 = 24°/3

x = 8°

Thus, The value of x is 8°
