If a deep-ocean trench is located adjacent to a continent, active volcanoes would likely be found

The answer is Landward from the trench. Such mountain ranges are formed at convergent boundaries as two tectonic plates, moving in opposite directions, collide. As the oceanic plate is subducted, since its denser, it begins to melt to form magma. The magma rises and erupts to form the mountain ranges landwards on the overlying continental tectonic plate. A trench is characteristic of a subduction zone but cannot be offshore but rather onshore in the deep trench of the oceans.

for e2020. the answer would be some directions from the mountain range so we can find mt. whitney. to locate which direction is north, you should use a   compass. this would not only find mt. whitney, but also becuase of this long paragraph you would get points because it's not like anyone actually reads your work becuase once they read the first sentence it sounds dumb enough to not read becuase i'm not good at answering this but the answer is compass for your benefit.

for e2020 ; -;
