Step-by-step explanation:




Angle 1 is 79
Angle 2 is 11.
Answer:
Step-by-step explanation:
16
The surface is parameterized by

and the normal to the surface is given by the cross product of the partial derivatives of
:

It looks like you're given

Then the normal vector is

Now, the point (2, 2, 0) corresponds to u and v such that

and solving gives
, so the normal vector at the point we care about is

Then the equation of the tangent plane is
