Two angles with measures (6x + 60) (90)<br> are supplementary. What is the value of x?
fredd [130]
Supplementary angles add up to 180, so
6x+60+90 = 180 and solve for x
6x= 30
x=5

What is the value of x in the measure of the angle?
Andrew [12]
The two angles would be both 41 degrees.
(2x  + 13) = 41 \\ 2x = 41 - 13 \\ 2x = 28 \\ x =  \frac{28}{2} \\ x = 14
x in this case would be 14 degrees.

What are the forces that hold sodium and chloride ions together?
Phantasy [73]
Sodium is a metal, Chloride is a non-metal.

Right off the bat, you know that in order for both of these atoms to achieve a full valence shell that the metal has to lose electrons, and the non-metal has to gain them.

Therefore, you have the transfer of electrons in this bond in order to form ions.
Na+ and Cl-. This transfer of electrons in a bond is called an {{ Ionic Bond}}
