Step-by-step explanation:
The equation of the shpere canterd at point
with radius
is

The center of the sphere is (2,-9,1), the radius is 2, then the equation is

Now, find the intersection of this sphere with the plane z=2. Substitute 2 instead of z into the sphere equation:

This is the equation of the circle lying in the plane z=2 with center at (2,-9,2) and radius 
Answer:
92°
Step-by-step explanation:
because 1 is parallel to the 92°
If you know how to multiply, I'm sure you know how to divide too... But here are some.
4 and 2
8 and 2
6 and 3 or 2
I need to see the function In order to do this
