We know that
<span>the rotation of a solid does not modify the values of the internal angles of the solid
</span>therefore
interior angle after 90° rotation=interior angle before 90° rotation
interior angle after 90° rotation=108°
the answer is the option D 108 °
<span>-4x + y = -25 y = 4x - 25
-6x - 6y = 0 </span>
-6x - 6(4x - 25) = 0
-6x - 24x + 150 = 0
-30x + 150 = 0
-30x = -150
x = 5
y = 4(5) - 25
y = 20 - 25
y = -5
(5, -5)
Sulfur is an exception to the octet rule because it can have an expanded valence shell that holds more than 8 electrons. Common examples are sulfur tetrafluoride which has 10 valence electrons and sulfur hexafluoride which has 12 valence electrons.
However, there are no sulfur compounds with less than 8 valence electrons. So, the answer is false.
Answer:
the answer is about 8 cuz the answer shows 7.12 if you divide mentally
