Answer:
they give you its a right angle. right angle means its 90 degrees. to find x simply just subtract 62 from 90
Let
. The gradient of
at the point (1, 0, 0) is the normal vector to the surface, which is also orthogonal to the tangent plane at this point.
So the tangent plane has equation

Compute the gradient:

Evaluate the gradient at the given point:

Then the equation of the tangent plane is

You multiply 8x4=32 and then divide 32÷2= 16in²
Answer:
A
Step-by-step explanation:
sin 214 = -0.5591
tan 214 = 0.6745
cos 214 = -0.8290
I can’t see so sry try a different angle
