Answer:
The answer would be 11.51
Step-by-step explanation:
π is rougroughly 3.14
√70 = 8.37
3.14 + 8.37 = 11.51
Yes. If the diagonals bisect the angles, the quadrilateral is always a parallelogram, specifically, a rhombus.
Consider quadrilateral ABCD. If diagonal AC bisects angles A and C, then ΔACB is congruent to ΔACD (ASA). Hence AB=AD and BC=CD (CPCTC).
Likewise, if diagonal BD bisects angles B and D, triangles BDA and BDC are congruent, thus AB=BC and AD=CD. (CPCTC again). Now, we have AB=BC=CD=AD, so the figure is a rhombus, hence a parallelogram.
Answer:
x = 3 and x = -3 (aka. x = ±3)
Step-by-step explanation:
2x² - 18 = 0
x² - 9 = 0
x² = 9
x = ±3
Therefore, x = 3 and x = -3
