Answer:
75
Step-by-step explanation:
angle 2 and angle 6 are corresponding angles, because the lines are parallel and cut by a transversal, corresponding angles are congruent, thus if angle 2 is 75 degrees then angle 6 is 75 degrees
15s=350+100
15s=450
s=450/15
s=30

Under the given transformation, the Jacobian and its determinant are
so that
where is the region transformed into the - plane. The remaining integral is the twice the area of .
Now, the integral over is
but through the given transformation, the boundary of is the set of equations,
We require that , and the last equation tells us that we would also need . This means and , so that the integral over is
