Answer:
Step-by-step explanation:
3(x + 2) = 3*x + 3*2
= 3x + 6
Cos x=5/12. Solve for x which is 65.37 degrees.
Flip the x and y like in the coordinate plane x,y not y,x
In the first octant, the given plane forms a triangle with vertices corresponding to the plane's intercepts along each axis.



Now that we know the vertices of the surface

, we can parameterize it by

where

and

. The surface element is

With respect to our parameterization, we have

, so the surface integral is
