In the figure, a//b , and both lines are intersected by transversal t. Complete the statements to prove that ∠2 and ∠8 are supplementary angles.
(given)
m∠2 = m∠7 (alternate interior angles theorem, alternate exterior angles theorem, vertical angles theorem, definition of supplementary angles)
m∠7 + m∠8 = 180° (linear pair theorem, verticals angles theorem, same side interior angles theorem, alternate exterior angles theorem)
m∠2 + m∠8 = 180° (Substitution Property)
∠2 and ∠8 are supplementary (definition of supplementary angles)

Determine whether the following statements are true and give an explanation or counterexample. bold a. when using the shell method, the axis of the cylindrical shells is parallel to the axis of revolution. bold b. if a region is revolved about the y-axis, then the shell method must be used. bold c. if a region is revolved about the x-axis, then in principle it is possible to use the disk/washer method and integrate with respect to x or the shell method and integrate with respect to y.
