Properties of a rhombus:
1. the all sides are equal
2. opposite angles are equal
3. consecutive angles are supplementary
4. The diagonals bisect the angles.
5. The diagonals are perpendicular bisectors of each other.
==================================================
∵ abcd is <span>a rhombus:
</span>
<span>∴ ∠ abc = 2 ∠ebc = 2 * 36° = 72° ⇒⇒⇒ property number (4)
</span>
<span>∴ ∠ dab = 180 - ∠abc = 180° - 72° = 108° </span><span>⇒⇒⇒ property number (3)
</span>
∴ ∠ dae = 108°/2 = 54° <span>⇒⇒⇒ property number (4)

Answer:
switch the 0.8 in the 2nd slot so it looks like 70% 0.8 0.699 3/5 (0.6)
Step-by-step explanation:
A four-dimensional space or 4D space is a mathematical extension of the concept of three-dimensional or 3D space. Three-dimensional space is the simplest possible generalization of the observation that only three numbers, called dimensions, are needed to describe the size or position of objects in the everyday world. For example, the volume of a rectangular box is found by measuring its length (usually labeled x), width (y), and depth (z).
