A rectangle or a parallelogram is a polygon with only 2 congruent sides and 2 congruent angles.
I assume
has counterclockwise orientation when viewed from above.
By Stokes' theorem,

so we first compute the curl:


Then parameterize
by

where the
-component is obtained from

with
and
.
Take the normal vector to
to be

Then the line integral is equal in value to the surface integral,



<span>Reason:
<u>The angle between tangents and angle subtended by radii are supplementary</u></span><u>∠BAP = 90° </u>
x = 180 - 73 = 107°
Answer: x = 107°
This is what I learned:
D = Divide
M = Multiply
S = Subtract
B = Bring down
C= Check
D= Dad
M= Mom
S= Sister
B= Brother
C= Cousin
Hope this helped you! :)
