I'm pretty sure as the workers elevates to the top, the angles grow bigger (obtuse). As they descend, the angles become smaller (acute). Not very positive on the terms, ahah.
Answer:
81
Step-by-step explanation:
RZT = 137
RZS = 56
SZT = 137 - 56 = 81
A. it has 11 electrons.
b. the elctron configuration is 2,8,1
c. when sodium ionizes it loses 1 electron because it is easier to lose 1 rather than gain 7. hope it was helpful.
Answer:
For the given circle, the center is at (-7,4) and radius is 7
Step-by-step explanation:
Given equation of the circle is ![(x+7)^2+(y-4)^2=49\hfill (1)](https://tex.z-dn.net/?f=%28x%2B7%29%5E2%2B%28y-4%29%5E2%3D49%5Chfill%20%281%29)
To find the center and radius of given circle with the help of its equation:
Equation of the circle is of the form
(x-h)^2+(y-k)^2=r^2\hfill (2)[/tex] with center at (h,k) and radius is r.
Given ![(x+7)^2+(y-4)^2=49](https://tex.z-dn.net/?f=%28x%2B7%29%5E2%2B%28y-4%29%5E2%3D49)
The above equation can be written as,
![(x-(-7))^2+(y-4)^2=7^2\hfill (3)](https://tex.z-dn.net/?f=%28x-%28-7%29%29%5E2%2B%28y-4%29%5E2%3D7%5E2%5Chfill%20%283%29)
Now comparing the equations (2) and (3) we get
h=-7, k=4 and r=7
Therefore center at (h,k) is (-7,4) and radius is 7
For the given circle, the center is at (-7,4) and radius is 7
